Why do we like rain?

Why do we like rain? there has to be some sort of logical explanation for it, So I'm going to logically find an explanation for this. First of all I guess most of you can relate ( maybe most cant, but whatever) that Rain makes you feel new, refreshed and energized. Lets rationalize this, what if these feelings are some sort of left over / or not evolutionary reflexes. So what do I mean by evolutionary reflexes?  well Primitive instincts so to speak it could be as simple as you kicking the doctor when he hits your knee with that rubber hammer thingy or someone getting this strange feeling that something is about to happen and then ten minutes later a freak storm appears, basically I'm talking about feelings which have maybe helped our great great great .. ancestors survive or kick their buddies, So what has rain got to do with any of it? Lets hypothesize...

Water means life, for our ancestors rain meant that they wont go thirsty for awhile and they would have abundant crops and they wont go hungry ( if they had given up their hunting gathering ways that is ). So rain literally did mean relief and new beginnings and hope and all that stuff. So according to this I like rain because apparently I get really excited about my new (hypothetical) crop.... I hope I'm not over simplifying things here.

Even if it is because of the bogus reason I gave the effects of rain are undeniable, The very fact that I believe that I can do anything in the world on a Sunday night even when being acutely aware of the Monday morning looming ahead is a testament to the mood uplifting and perhaps hallucinogenic qualities the of rain on the brain.

Note: I think I'm going to do some scientificy and actual research(read Google) on this and post up.
