And if there's water but no life, we're going to somehow have Noah's Ark in a storeroom on the spaceship? What if it has critters something like dinosaurs? They will have spent their entire evolutionary process in the presence of that planet's gravitational field, which will almost certainly be significantly stronger than ours.
So in waltz earthlings, in a weakened state, promptly fall on their faces and can't get up.
Oh boy. Sign me up.
I say put a robotically placed telescope on the moon and send robotic missions out to explore the solar system and maybe beyond. The rest is fantasy booooo-$h!t.

I'm sure someone said something like that about sailing off the edge of the earth, space flight, sound barrier, etc, etc. 100 years ago, if you told someone what we would have today, it too would be fantasy if not physically impossible. There were all kinds of things that could happen if you exceeded the sound barrier. It couldn't even be done and we would be foolish to speculate on what would happen if it could. There was a time we could not go beyond a certain point in the sea or monsters would eat us alive too. And if you told someone that someday we could travel underwater, well, you should be locked up.
