If there so many planets out there in space why aren't there any human colonies on other planets?

How would you really know if there were or weren't?

Because earth was created to be our home, that is it's purpose. Besides, humans would just abuse and disrespect any other planet as they have earth.

@Magenta We cannot of course know if there are equivalents elsewhere - there is no logical reason for there not to be - but we can only hope their inhabitants are not as messy and destructive as our lot.
Magenta · F
@ArishMell No, we can't know definitively, but I don't believe there are.

One other than the planets in this solar system humans can not get to any of them not for sure if they can get Pluto or Uranus or Neptune.

Where there is no oxygen humans cannot exist.

Where there is no earthly food humans cannot exist.

Where there is no fresh earthly water humans cannot exist.

And humans don't have the technology to terraform it or build on it definitely not able to get there you know how much rocket fuel letter take.

@Learninglife9 It may not take ever so much fuel because once a spacecraft has been accelerated to its cruising speed the engines are turned off and it keeps going at that speed.

You are right though - no other planets in the Solar System can support human life: Mars is the only one we may be able to visit but we would not be able to walk about on it without space-suits. The others would be even more deadly.

Then there is the matter of time to reach them... oh, and does anyone want to come home?

How can you be so sure that Mankind doesn’t exist anywhere else on other planets?
ArishMell · 70-79, M
There may be, or at least creatures similar to us - not as colonies in the settler sense, but native to their planets.

However, we cannot know this; and we have no foreseeable way to colonise them.

Even our nearest planet theoretically viable for human visits - Mars - would be a very unpleasant destination no-one would want to "colonise".

What if humans were from another planet and we crash landed here million years ago.

What if all humans are the illegal aliens?
ArishMell · 70-79, M
@HumanEarth Theory? Fantasy!

If it had happened, it would raise one or two very awkward questions indeed.
HumanEarth · 56-60, F
If it was written by a globalists and wanted to promote climate change. Then say they destroyed their home planet.

They would push the fact idea.

Like the whole life on Mars thing and them escaping the planet and crashing here. That's one crazy story I heard
ArishMell · 70-79, M
@HumanEarth That fable you heard seems suspiciously lifted from a short science-fiction story I once read.

I forget the title and author but it was a sequel to H.G. Wells' The War Of The Worlds.

The premise was modern-day explorers from Earth, finding on Mars the remains of those Martian would-be invaders' own world, all now empty. The discoverers realised that the Martians gate-crashing of Earth was an attempt to survive as their own planet became the uninhabitable desert we know it as.
Because we have neither the money nor technology to acheive such a thing.
