....yes, bacteria could have traveled to/from earth to start life. I saw a program today about it, and they ran tests on samples of bacteria, firing them from a rifle. They found the bacteria could easilly survive 100000 G's of acceleration, and 300000G of deceleration. They theorised that in the instant after the impact, the bacteria would reform themselves back to normal. To confirm it, they did a test in 0 gravity, and saw that the bacteria didn't re-arange properly. They worked out that the bacteria use a gravitational field (ie of a planet) to realign themselves.
What this means for life on other planets, i dont know :doh:
Perhaps an alien race has no religion. Perhaps it is one hive mind and has no intrest in religion or how it got there, only its future expansion. A race of mind readers (theres a bigger word ending in ...path but i cant think of it) could evolve into one single mind. Similar to the Borg, except not mechanical.
I think its just our curiosity as humans that drives us to wonder where we came from. And religion is the product of fear of where we might have come from. I mean, what if we found out we are just bacteria living in the feicies of galaxy sized creatures? Would you accept it? No, you'd create a religion to tell you you are here to make peace and happiness.
Personally i neve think much about where life on earth came from, i tend to think more about where i came from. Technically i am just a conseince being fed sensory input. And how do i know that what i am told happened before i was born, did actually happen? How do i know anything before exactly now happened? All i have to go on is memories, and what can they really proove?
I've gone crazy (again). Good night people.
