People need to understand that creationism does not mean evolution can't also be happening. The Lord God set things in motion and gave us free will to make our own minds up about things. He doesn't demand that we believe in Jesus he just presents us the opportunity to believe and I believe that the same is true of this issue. The Lord God gives us information and the ability to decide for ourselves, and I have done that and I believe the Lord God set evolution in motion when he created the heavens ans the earth and even any E.T.s there might be.
The Bible does not tell us there are no others out there.
Remember the Bible is the word of God as seen by men who are relating what they believe many years after the events depicted took place and we all know things can be misinterpreted by man.
