That's not what I said at all actually. I'll reserve judgement until I see actual evidence of alien life, which is what scientific thinking is based on, not blind faith. You think it might be out there, a scientist will go looking for it to prove it's out there, a theist will tell you to just believe it is because that's what you've been told.
You're welcome to whatever beliefs and views you hold; some of us have a background of personal experience as well as study that tends towards evidence against a benevolent God rather than for. Each to their own.
My background is more towards the history and psychology stuff, not pure science anyway, but what that tells me is that oral histories are notoriously unreliable, that (like others have mentioned) religious texts were at least partly written to drive societal behaviour in their time (e.g. burying of dead bodies was mentioned, prohibitions against eating certain foods is another one - phrased as 'God says so' but realistically to drive behaviours around sanitation and hygiene), and that there are basic commonalities between all major religions (the do unto others stuff etc) - if you study it, it's even possible to pinpoint at which points in world history one group became dominant over another, brought their religious tradition in with them but cribbed the bits they liked from the locals (or took on certain aspects to make the religious takeover more palatable to the natives). That's why I refer to Christianity as the western cultural mythology. All cultures have them, that just happens to have been the dominant one in the time and location I was - utterly randomly - born into.
