What is a good question but I find why to be ever so much more interesting. Why, for instance, does life try so dang hard to survive?
The "Will to Live" is #3 of my nine challenges on this thread: post 40 on the Does Science Point to God thread
Thank you for your post!!!
Because natural selection favors the life forms which do.
Things which "try hard" to survive are more likely to be prominent in the biosphere than things that don't.
