I'd say the fact that humans metabolize alcohol (have evolved it) it's a pretty good hint that there was an evolutionary pressure selecting for it.

I'm not sure about evolutionary reason "for" drinking. As I understand, when alcohol is digested, the body switches to metabolising it immediately. So, yes, there is a pathway, but it can be argued that alcohol is recognised as toxin, so the evolutionary pressure was to get it out of the system ASAP. Therefore, it is metabolized, but still "bad for you".
