No. I believe life is precious, and only ever existed or will ever exist on earth. I also think the earth is only 5000 years old. And I fuck my sister.
intelligent life? or biological enzymes?
either way, i believe in proof... simply saying, "there HAS to be other intelligent life in the universe, we can't be the only one!!!" is not proof.
the observable universe is approximately 13.5 billion lightyears outside of our earth and visible to us at present day. yet we have not found any signs of intelligent life or planets capable of sustaining life like earth. there are similar planets that have recently been discovered but there is still no actual evidence of life elsewhere.
so, the long answer - Q: "do i believe in extraterrestrial life?" - A: not really!
LOOOOOOOOOL you don't
Exactly. But if you don't believe there is intelligent life out there then you should throw out all you know about science. There is no way that the universe is what our scientists say it is (ie 13 billion years old, speed of light is ___km/s, etc) because the same observations that give us those conclusions can also be made to conclude that there is clearly other intelligent life out there.
what efforts ?
we can't explore our own oceans, don't talk to me about space
