I am one of those christians who is very faithful in his religeon, yet never goes to church.... I am 13, and have been very interested in leanring as much as i can about my religeon... but I am confortable speaking from a purely scientific veiw If the universe was created suddenly, whether this was its first or second or billionth time (closed universe theory) and eventually the planets were formed, roughly the same time i would imagine, also I think the elements would be evenly distributed throughout the universe if it was suddenly formed by a "big bang" scenerio. So if there was life, maybe on the other side of the universe, it would have been created, sparked and evolved about the same time and rate as us. I think it would have taken no longer for single cellualr organisims to evolve into more complex organisms here than on the other side of the universe if that is true, and therefore the rest of evolution would continue at still about the same rate. If there are other 'intelligent' lifeforms in the galaxy wouldn't they be at the same evolutionary stage as we are, or within a few hundred years give or take? I strongly beleive that there are other lifeforms out there, but even if there were I do not beleive we would make contact with them until both our races are technologically advanced to a high enough level to travel through large areas of space, maybe meeting somewhere in the middle of Earth and whatever planet they evolved on. Of course there are thousands of variables that would effect the course of evolution, so the space between us may very well be a thousand years if not more, but that could be less advanced than us or more advanced. Imagine the universe as a circular object, which it is if the big bang is true and I think it was proven anyway... but if we were somewhere on one side and a second intelligent life form at the other side and each race is advancing relativly steadily at about the same rate as the other. From the home planet they and we begin expanding outward, radially... depending on the technological and evolutionary level the two would meet somewhere in the middle, unless one race was far more advanced, then the meeting place would be closer to the more primitive planet. If we were the more primitive planet (assuming my theory is completely wrong) then the more advanced race would be slowely apraocing us as they explore (radially) from their own planet. Or maybe they have already found us, maybe through advanced science they were to pinpoint another planet capable of life so they went straight to us... our own sciences are not to far from that, we have guesses on which stars may have planets able to support life. But either way if another or multiple alien races exist it is only a matter of time until we meet, or maybe we already have. It is litterally a ticking eggtimer until our races meet somewhere in the middle. slightly off topic i know but it is an important part of the topic.
