IF God created humans (and all the other living beings ), it must have been a curious experiment (at first) that went bizarrely amiss, and now s/he can't do anything to control the mess, and decided to just let it run it's course.

Personally, I don't think the "creation" was created -- it was a scientific evolution that ...errr... just happened. What happened, what happens, and what will happen (apart from how we choose to live) is beyond our control, so just accept (life) and live it. When we die -- when our brains stop functioning, our minds cannot think, and our bodies lay useless -- nothing will matter anyway.

Making the most out of life is to just live it, moment by moment, and only cherish it while you still are able to think and feel. So, don't think too much!
