Belief in God, gods, spirits etc are all taught to people, hence you have churches, temples, bible study, Islamic schools etc.
The creator god concept comes from a very basic mistake in logic: The assumption that we just have to find the right god who made all this stuff.
No-one seriously questions the assumption that there is a god in the first place (because the argument would collapse). Also, how do you prove it was not 3 gods who made everything or 33 for that matter?
The concept of God/ gods serves an emotional function for human beings. i.e.: That there is ultimately a way to control your experience (because even if you are not in charge the god / goddess is) This provides immense comfort and solace when things get out of control: sudden deaths in the family, change of fortune etc. Its a coping mechanism thats thousands of years old. The problem with the concept is that its only as good as what we can image it to be. If people are aggressive and war-like, their chosen deity simply reflects that. And the reverse as well.
At the end of the day the Buddha spoke against it as wrong view as it is another manifestation of tanha and upadana based on avijja. So whether you are monistic, monotheistic, polytheistic, henotheistic etc. Whatever point of attachment you have, no matter how sublime the experience or refined the argument, if you cling to it, you suffer.
Thats the whole point of Dhamma (utterly unique in this world). He didn't teach to give us more things to build up and cling to. Especially ditthi (views) The best view is right view (samma ditthi) that leads to the end of attachment to all views. Fools try to cover the earth with leather, the wise put on sandals. Sadhu X3
Natthi me saranam annam buddho me saranam varam
For me there is no other refuge, the Buddha is my excellent refuge.
