Random thought

I do a lot of thinking and my regular thought process is usually goes along the lines of me watching people and continually asking why we do stuff. Just about everyday when I go to school I see people interact with each other and I always ask why? Why are we nice to each other? Why are we mean to each other? Why do we care about each other? Why don't we care about each other? Since I'm a man of science it usually all roots back to the basic reasons for living which is surviving and reproducing. Thats not a new thought though people have realized that before so I dig deeper why do we want to survive and why do we want to reproduce? that leads into genes and the fact that were naturally programmed to pass on our genes. This is where my thought process gets hazy. I'm no scientist so most of this is just theories and stuff in my head. Which might explain why I always can't dig deeper then genes. I mean genes are made up of what? Chemicals. Could it be that we're all just a huge chemical reaction? and how do all these chemicals react to make us do the things we do? It's not like chemicals have thoughts or plans for us they just react in a way that gives us life..

any how if that made any sense to anyone let me know and help me with my theories I always like to see other peoples point of view. if it didn't make sense don't feel bad I was kinda just rambling on here I don't even know if it makes sense I just kinda wrote down my thought process.

In conclusion.... Am I crazy?
