Considering that eyewitnesses testimonies are one of the single most unreliable forms of evidence?

Things that were once thought of as an act of God are now understood and have a reasonable explanation and I don't really believe that people have seen God or Angels. I do believe that we just didn't happen and that we are a result of intelligent design. I don't think the human race is even close on figuring out the how and why of our being and all about God, etc. I just don't think it is exactly as the Bible teaches
