Well, I think you don't mean "aliens don't exist" but "aliens are on Earth".
There's evidence there is life around Venus. That's be alien life.

Those are two different concepts. I'm not aware of any theory suggesting the speed of light can be exceeded. Except by the rate of expansion of space, which can expand faster than the speed of light (hence the "cosmic event horizon," defining the bounds of the "observable" universe)
The other concept you mentioned -- an Einstein-Rosen bridge, aka "worm hole" -- does not contradict the speed of light being a constraint that cannot be exceeded. It's a bijection of the fabric of spacetime. While it could theoretically allow travel between two distant points in space in a much shorter time than could be accomplished with linear travel through space, you wouldn't actually be moving at a velocity faster than the speed of light.

Humans are possibly millions of years old.
May be cataclysms have destroyed civilizations that were much advanced than ours ... that possessed a much higher technology than ours ....
Who knows....
290 million years ....Yes sir.
That touches on one of the proposed modifications to the Drake equation, known as the "reappearance factor." It proposes that once an intelligent civilization develops on a planet, even if that civilization ends due to some cataclysmic event, as long as all life is not extinguished on the planet, then the possibility is present for another civilization to eventually emerge. It would depend on the cataclysm, of course. The conditions on earth after a "nuclear winter" would be temporary and eventually return to normal, as opposed to conditions caused by a change in the sun that renders the earth uninhabitable (sun becoming a red giant, etc).

New laws of physics may exist that we don’t know of

There remains no evidence reflecting that alien life doesn't exist on other planets, period. The current estimate for the likelihood of habitable planets in our own galaxy is approximately 300 million and several within 30 light-years of our location. As it is estimated that there are as many as 300 million in our own galaxy that may be habitable and the current estimate number of galaxies being 2 trillion, that is a vast number of planets that may harbor life and to disregard the strong possibility of life not only in the milky-way galaxy, but in the 2 trillion other galaxies, shows a complete separation from reality.

What evidence around Venus? Venus has too much harsh gases.
If there were aliens, then we would've found evidene of them by now. Instead, we build a better telescope.

If there's life elsewhere, then I'd explore Europa and other planets where it looks like where we could live. Forget the other places.

Here's what I found on you.
The other I knew about you already. You have no answers even if your life depended on it.

Did we find signs of alien life in the clouds of Venus? Here’s what the experts say
The detection of a potential 'biomarker' for life on Venus has sparked hesitation, excitement and hope in scientists.
www.sciencefocus.com
"A paper released on Monday, 14 September, showed the detection of a mysterious molecule called phosphine in the clouds of Venus. Researchers say that molecule could be produced by living microbial cells."
Essentially the land surface is way too hot for life, probably, but the atmosphere might have life.
It's not about telescopes. This life is almost certainly not as developed as humans. It's probably very low down on the development scale. But alien life is life that isn't from this planet.

Jeez. If phosphine is a real sign of life, then it does make you wonder what kind of life can live in a harsh, harsh, harsh gaseous and chemical planet like that. It's sci-fin that Venusians could live but I always thought it would be unrealistic. If there were some kind of basic life there, then it would open up new heavenly bodies to explore. Maybe our planet isn't that polluted and global warming is an acceptable way of lifeDid we find signs of alien life in the clouds of Venus? Here’s what the experts say

Well, we know life can grow at the bottom of the oceans near sources of heat.
Global warming is a natural phenomenon, if it gets warmer life will still live here, it lived here under the dinosaurs. What might not be possible is humans living here. Hence the problem.

We always think we know more about science than we actually do.
Based on our current knowledge of physics faster than light travel is impossible. However at one time many felt breaking the speed of sound was also impossible for a human. I believe our knowledge will continue to grow as centuries pass and we may discover what we believe is impossible today is actually quite feasible.
Hidden in Einstein's Math: Faster-than-Light Travel?
Two physicists have extended Einstein's special relativity equations for faster-than-light travel, although no one knows if it's possible to move faster than the speed of light.
***snip***
Despite the singularity, Hill is not ready to accept that the speed of light is an insurmountable wall. He compared it to crossing the sound barrier. Before Chuck Yeager became the first person to travel faster than the speed of sound in 1947, many experts questioned whether it could be done. Scientists worried that the plane would disintegrate, or the human body wouldn't survive. Neither turned out to be true. …emphasis added.
Fears of crossing the light barrier may be similarly unfounded, Hill said.
"I think it's only a matter of time," he said. "Human ingenuity being what it is, it's going to happen, but maybe it will involve a transportation mechanism entirely different from anything presently envisaged."
Faster-Than-Light Travel is Possible, Theoretical Study Suggests | Sci.News
A new theoretical paper, published in the journal Classical and Quantum Gravity, reignites the debate about the possibility of superluminal (faster-than-light) travel based on conventional physics.

Humans could be living under an unbreakable dome above the pollution or under the sea below. It could be in places our generations could not imagine living in. Maybe we launch our garbage towards the sun. Even then, it would be better than living on Mars, Venus, or Europa.

Potentially yes, we have the technology.
However, the one thing humans are good at is fucking everything up.
We tell people to wear masks and they scream like petulant children. Can you imagine what they'd be like under a dome?

The Fermi paradox, named after Italian-American physicist Enrico Fermi, is the apparent contradiction between the lack of evidence for extraterrestrial life and various high estimates for their probability (such as some optimistic estimates for the Drake equation).[1][2]
The following are some of the facts and hypotheses that together serve to highlight the apparent contradiction:
en.wikipedia.org
Maybe intelligent life is extremely rare. Wolf like and dolphin like creatures are everywhere, but human like creatures are 1 in a trillion shot.
Or maybe we're the first. The most advanced and other intelligent alien species are less advanced.
Or maybe we're the only intelligent species in the universe.
The following are some of the facts and hypotheses that together serve to highlight the apparent contradiction:
- There are billions of stars in the Milky Way similar to the Sun.[3][4]
- With high probability, some of these stars have Earth-like planets in a circumstellar habitable zone.[5]
- Many of these stars, and hence their planets, are much older than the Sun.[6][7] If the Earth is typical, some may have developed intelligent life long ago.
- Some of these civilizations may have developed interstellar travel, a step humans are investigating now.
- Even at the slow pace of currently envisioned interstellar travel, the Milky Way galaxy could be completely traversed in a few million years.[8]
- And since many of the stars similar to the Sun are billions of years older, Earth should have already been visited by extraterrestrial civilizations, or at least their probes.[9]
- However, there is no convincing evidence that this has happened.[8]
