Yup , Ours is not the only star/Sun in all the solar systems with a third planet around it .
Yes, it seems unrealistic to think, that with all the worlds out there, that we would be the only one. Im sure that there is both life, and intelligent life out there.
Very much doubt if there isn't. But as for anything we can have an intelligent conversation with, I've a better chance with the toaster.
Of course. The question is will we find it before we all die out. I'd be happy with single celled organisms being found on europa or titan.
Without a doubt.
I think so - Our planet couldn't be the only one with life
