Are aliens really going to have to land on this planet

Are aliens really going to have to land on this planet right in front of us all before we take space travel seriously?

Trump is building wall around the heliosphere so no way.

Did the American Indians develop trans-Atlantic vessels after these guys showed up?

They never had the chance. Let us hope it is different in our case.

What would be the benefit of space travel? There are very few 4-star hotels in space.

Resources
Wealth-One asteroid cost at least ten trillion dollars that were discovered only a few years ago.
The ability to defend our planet from asteroids
Spreading our basket around instead of one place

Maybe even one day another planet like earth.

Many reasons.

Mining of asteroids isn't' commercially viable using our present rocket technology and lifting costs of $2200 per KG. If trillions of dollars of resources were to enter the markets the prices of those resources would plummet. This has happened before, when Spain began to bring back gold and silver from the New World. The subsequent crash in gold and silver prices created an inflationary spiral that crashed the economies of Europe for a century.

Catastrophic asteroid hits are millions of years apart.

An orbital or planet based colony would be more susceptible of catastrophe and at greater risk of extinction than the human population on Earth.

No earth-like exoplanets have yet to be discovered and were one discovered we don't have the technology to reach them without centuries long trips.

There is no pressing reason to develop space travel at this point in human development.

They already came here. They talked to the OP and realized there is no intelligent life here. So they left.

Great going spanky.

How about we work on the countries ability to defend against assholes first?

Long distance space travel is no viable currently. We can probably make a manned trip to Mars but that is about it. Technology has a long way to go to get even close to being able to travel near the speed of light which is what would be required before thinking of interstellar travel. The closest star is 4 light years away. Even at the speed of light it would take a ship 4 years to get there. Oxygen, water, waste recycle/disposal, life support, for 4 years for a flight that is likely to not find another habitable planet. Even if they arrived and did find a livable planet it would take the message four years to get back here and at minimum another 4 years for another ship to travel there. 12 years.

There is likely a way to travel through space at faster than light speed, but until it is found, if ever, we're stuck here. Unmanned spacecraft will have to lead the way.

We need to destroy Islam and Marxism before we spread humanity around the galaxy.

Yes!

They already have. No really, I heard it on youtube.

7 billion years ago any intelligent life had it easier than we do now. The universe after the big bang expanded and from what we know it's still expanding and picking up speed. So the stars were all a lot closer 6 billion or 9 billion years ago. Imagine what the night sky looked like ten billion years ago. It must have been amazing.

Now imagine how far apart stars will be ten billion years from now. So when a future species on another planet evolves at that time they may look out and only see 9 faint lights. So far they can only guess what they are. They may truly think they are alone.

So chances are if aliens visited it was before humans even evolved. The aliens instead visited before dinosaurs even evolved. They saw millions of trilobites and tardigrades

If Christianity says we're alone we need to drop it too the minute we find other life.

Actually in order to have it we need to research it and develop it. There is every reason to develop it. The more we work on it the cheaper the cost to lift off and maintain a presence in space. Some one WILL mine those asteroid eventually.

Except it says no such thing. But thanks for being clueless.

At some point they have to come and take you home, don't they?

I have no doubt of that. But, we won't be doing it with '60s rocket technology. Humans have been wading around in low-earth orbit for nearly 50 years with nothing to show for it. Technologies that could make exploitation of the solar system a profitable venture are still on the drawing boards. Mass drivers, space elevator, orbital hoist, not one of these things is being explored in any meaningful way.

Until they are, any kind of development of the solar system is a fantasy.

Yes it does. Christianity is a spin-off of the old testament. We are alone they say.

Does Christianity say we are not alone?

I'm sure in that book of ramblings it says both if you look and twist hard enough
