CBD, thanks for your compliments.

We need to reach to certain concret conclusion. If we have to assume the things then there's no meaning to questions. Accept as it is, saying that God told it and then there's a big full stop.

The question is why the purpose of human life to serve god?

What's the real purpose?

If god wants somebody to praise him only and that's the only purpose then just create advanced level of humans instantly and supply him with infintesome source of energy. (no need to give them stomach, hunger, lust, procreation powers).

So the question could be if the life is made with purpose or without purpose. Is it an accident or well thought plan?
