I could also get more happiness and security by constantly dosing myself with drugs and locking myself inside a vault.But if we did that nothing would be accomplished, we'd never advance and humanity would soon cease to exist.

So your argument is, "I believe in human rights because I like them." Because humans are sacks of chemicals, what does it matter if we survive or not? 

Don't begrudge therefore the religious for believing in God because they like Him.

But you have illustrated my point perfectly. Through unending demands for proof, you fall back upon, for example, an axiom that it is beneficial for humanity to survive. An idea which you cannot prove but believe because you want to. Welcome to the team.
