When people say life, do they mean intelligent, and if so define intelligent. Or are we talking microbial, or something?

Us being alive are proof that life can exist on a planet. To deny that it could happen on other planets only shows a denial of science.

Not known, and they surely aren't visiting earth.

The universe is unbelievably vast. There are over 100 billion stars in our Galaxy, and billions of galaxies in the Universe.

The odds are that somewhere out there there is life. In the billions of trillions of planets it’s not just likely but almost certain.

No way to know.

Going off of pure probability I would be surprised if there's nothing at all out there, but going of off the sheer size of the universe I'd also be surprised if we ever encountered an extraterrestrial lifeform,let alone civilization

The only answer either of you should be arguing is that it's not know yet

The Fermi paradox says yes. Whether we ever meet them or not is a far different question.

At this point in time, I don't know. I think that it is almost impossible that life hasn't existed somewhere else in the universe, at some point, in the billions of years that it has existed.

I just finished the first episode of the podcast - it's really cool! Definitely looking forward to the rest of it.

I’m thankful we live in a time where cameras exist so we CAN see this stuff. It’s like we have cybernetic eyeballs :)

I hate this headline more than anything I've seen today.

I know the feeling. I haven't read anything in the last year or more. Hard to find time

Yes but if you don't have the most basic understanding of science, you could just start by reading up on it and getting a more general education. Then you might have more well thought out questions instead of the stuff i see here all time.

WE won't do anything substantial to Mars. The Martians will, once there are millions of them, if they have enough desire for it.

Sorry to burst your habitat dome, but cool season grasses don't grow below 40F (4C). There are no trees or shrubs on Antarctica. The permafrost prevents root growth. The Curiosity rover which is near the equator, sees nighttime temperatures below -100F (-73C).

You can grow things under a temperature-controlled dome, but not out in the open on Mars today.

Could we do it? Sure. But why? It would be far, far less energy intensive and more cost effective to desalinate/decontaminate water already on Earth than go millions of miles to harvest a few spaceships worth of ice.

Hello u/zephyer19, your submission "Could they move ice from the planets to Earth?" has been removed from r/space because:

• Such questions should be asked in the "All space questions" thread stickied at the top of the sub.

Please read the rules in the sidebar and check r/space for duplicate submissions before posting. If you have any questions about this removal please message the r/space moderators. Thank you.

Looking for fresh water? I would think desalinating sea water would be more cost effective.

Theoretically I think it's possible (even though this is not my area of expertise), but the ethics of this are risky. Ice from other planets could hold contagions which could cause unknown damage to our ecosystem. It would be an expensive way to bring about another mass extinction event
