a few times in the past i have seen things fly by in the sky & i couldn't for the life of me make out what the hell it was i am sure a lot of us have had this experience as a conspiracy theorist/truther i do believe that we are not the only form of life out there & that there actually is in reality other forms of life on other planets & that aliens do actually exist & that they are already here on earth but the governments of the world are just keeping them secret even though some people already know there real & out there cause of Roswell but i would like to here you're opinions what do you guys think do aliens really exist or not??.
I personally do not believe in aliens. We now know for a fact, the closest place any alien could come from is hundreds of light years away. Now, we can SAY anything is possible. I will not say that aliens are impossible. I just don't believe in them. I would have to see concrete proof that is irrefutable and then I have about a bazillion questions.
I have witnessed UFOs. I firmly believe there is a rational explanation although I don't know what that explanation is. I believe there are unexplained phenomenon. The absence of explanation does not cause me to believe in a fantasy.
Some people like to speculate, because we see life here on Earth and because we see trillions of stars, many with planets like ours, that almost certainly there is life elsewhere. I cannot dispute that our 92 fundamental elements comprise everything in our physical universe including life. However, all life is not intelligent. For life to evolve to our state of intelligence, I think it takes a special combination of things happening in a precise order and to precise degrees.
We have a very intricate and specific ecosystem which enables life. Dozens of random (or maybe not so random) factors are in play. For life to exist as we know it, think of all the things that MUST be as they have been? First, the proximity of the planet has to be close to the sun but not too close. It's orbit cannot carry it beyond a certain range or water would freeze solid and life couldn't thrive, if it could even exist at all. The orbit can't carry us too close or we'd all burn up. So a planet has to be in a zone where water is fluid on a constant basis. Another thing that makes this possible is our atmospheric pressure. Certain places on Mars have similar temperatures to Earth at certain times but the temps are not consistent because Mars lacks the atmospheric pressure of Earth. So that "perfect spot" on Mars might be 600 degrees or -200 degrees depending on time of day or night.
We've only been looking out into space for a short time and we've only barely scratched the surface but from what we have seen, we realize that planets like Earth are rare. Many are completely uninhabitable and unable to support any kind of life as we know it. You need liquid water, an abundance of oxygen, atmospheric pressure to keep it all stable... and something else you probably need... Seasons.
Way back in time, a giant celestial body collided with the Earth. The subsequent debris from that collision resulted in our Moon. It also set our planet on it's perpetually wobbly motion which gives us the four seasons. The Moon provides ocean tides. The seasons and tides are vitally important to millions of life forms. If you believe in Darwinian evolution, it is impossible for us to be here without the Moon and seasons.
So whenever we objectively evaluate all the thousands and thousands of parameters and aspects regarding our planet and life, we have to conclude that intelligent life as we know it is a rare thing in our universe. Is there the possibility of life as we
don't know it? Sure. And I actually think there IS microbial life all throughout the universe. Perhaps even in our own solar system... after all, the same 92 elements which give us life on earth can give us life elsewhere, the universe is all comprised of the same elements.
