I don't know where life came from. I know that I have listened and will still listen to all the theories out there and discard the ones that make no sense. I've posted that the first theory I was presented, a god, I believed for a while, and then I just couldn't believe that one anymore.
You said it was "humorous" to you that some say life came from another planet, ask where that life came from, yet you are perfectly comfortable saying a god that was always here made a man out of dirt. You think everyone should accept that with no questions. So of course I wonder why you can't accept life from another planet that "was always there". The same thing applies to your question about life beginning "spontaneously". Why not? If you believe a god that was always here can make a man out of dirt, why couldn't either of the other theories you mentioned be true?
Bill has said that the bible is his "user manual". A book that was written by superstitious men, ignorant of the facts is his user manual. (Ignorant of the facts does not mean ignorant, can't wait to see them run with that one). How is the bible any different than other people's theories based on their knowledge, experiments, and what others have done and written about that influenced their thinking? Their "user manuals" if you will.
If a scientist from a hundred or more years ago wrote down his theories, people accepted them until other scientists came along and added to, took away from, or changed something about that theory because of their findings, the believers point to that as total ignorance on the part of all scientists. (They don't know, they always contradict each other) etc. But they don't do the same when it comes to the bible, (oh it doesn't mean that, that doesn't apply anymore, that was written before man knew blah blah-it's still "the word"), and we're somehow wrong by pointing out the flaws in bill's "user manual".
Unless the world can survive for another million years, and probably not even then, man will never know how we came to be here. Whatever happened to put us here has "moved on" so to speak, it has no interest in us, we're not going to "meet it in the sky".
If you believe you will that is fine. But please don't insist I have to believe it, teach it to my children, or allow others to teach it to them in their schools. Please don't use it to discriminate and mistreat people you see as different and don't follow your "user manual". Please keep it out of my politics. Stop fighting wars because of it. As a group hold others (such as Camping) accountable when they use religion to prey on the elderly, fearful and gullible to take their money.
