ET vs God

I used to call myself an agnostic, but according to this, I would be an agnostic atheist IE disbelieving in any gods, but open to the possibility they might exist. What does this have to do with ET and God? Well, it shows the same philosophy need not just be applied to religion, but fits well with little green( or grey ) men too. Both have their adherents, and personally I doubt flying saucers are whizzing around just as I doubt God sat on a cloud dictating to Moses how to live right. I do however, think even though it is very unlikely, the possibility of little space aliens visiting earth is a lot greater than God telling Noah to build in ark, with nowhere near enough genetic diversity to repopulate the animal kingdom.
The Christian god is based of a book, the bible, Christians are supposed to take on "faith" without any evidence or proof that what it says is true. Indeed, much of it goes against modern scientific theory, which unlike religion, has to undergo peer review. An example of this would be the age of the earth, which differ greatly according to the bible and scientists. So there is not much, (if any) proof of God whipping up the earth in seven days, then spending the rest of his time berating his favorite creation, man for bad behavior. Same goes for the little grey fellows, just a bunch of fuzzy, fake looking pictures and peoples claims to have seen them. Looks the same as far as evidence goes, however when you delve into possibility(although again, can't repeat this enough, both are unlikely) it gets interesting. There is just no precedent, or example for God, we can't say, look at that creature, we saw him through a telescope whipping up a world in seven days. There is, however, a race that went from grubbing in the dirt and throwing rocks to going into space. That's us, of course. While we can't currently get to other stars, there is a possibility that with better technology it could get done, although it would be a long, slow voyage requiring either a generation ship or some sort of Cryopreservation. There are millions of stars, so the possibility some other species could have evolved intelligence is pretty good. If they were older, or their civilization lacked a Dark Age there is a possibility their science would be more advanced, allowing them to build a starship. Notice I have NOT suggested a faster than light ship, as physics has proved that to be impossible. The Enterprise belongs with Jesus, you need FAITH to make that bad boy go! So while there are no budding examples to show God, human evolution and advancement at least shows that another race, capable of space travel is possible. Due to the enormous cost of building such a ship, and the fact that the Earth is located at pretty much the end of the Galaxy, make any such contact extremely unlikely. More possible than God, but still unlikely.
