When you consider that this planet is one in billions, it is statistically impossible for there not to be life on other planets.

to what degree?

p<0.05 ?

p<0.01 ?

Like what a lot of people have already said, i think there's a high chance there is life on other planets. Just life that has adapted to those sorts of living conditions, like we have on earth. Maybe not in our galaxy, but probably in a different one

This stuff realllly interests mei think anything to do with life on other planets/how the world was created/human life is fascinating

me too

I really hope much more is found out on this topic before i die

It bugs me when people say there can't be life on other planets because there's no oxygen/too little heat etcjust because these factors are needed for humans to survive, doesn't mean these factors billions of miles away are needed for 'Moomins' to survive (silly name i just thought of for the possible life somewhere else)

There could be galaxies that are kinda parallel to the milky way, with the same planets inone of which has similar properties to Earth

Parallel universes are such an interesting theory

Another thing has to be taken into consideration:

There may be, or may have been life elsewhere in another galaxy that's thousands of light-years away.  So it would take even the speed of light thousands of years to reach us, or vice-versa.  By this time, any lifeform that has sent out signals in forms of radio waves (which are a lot slower that the speed of light and would take considerably longer to reach us) may have become extinct, just like life on Earth has done many of times thoughout history.

I'm not sure if I've explained that very well, so I'll try and use an example, lol:

Say there was intelligent life in a galaxy say for example 2 million light-years from Earth and this lifeform had sent out signals via radio waves or whatever like us humans have done.  These radio waves would not be travelling anywhere near the speed of light, which would take 2 million years to reach us alone; they would take a lot longer.  During this time, that entire lifeform could have been wiped out, or should it still exist then it would possibly be thousands of years (possibly millions if it's in a galaxy millions of light-years away) ahead of us in terms of technological advances.  

I do think that there has been life at some time or another in the Universe.  Whether it is still in existence who knows... we will probably never know due to the vast size of the Universe.
