Yes, i see your point. I belief this is because people are not sincere, not truthful, deceiving themselves and others, influenced by craving. Sorry for the judgements but i belief this is true. I will try to explain.
Is there really someone who can claim to have direct knowledge of an eternal being, a creator? How would one know this? Does one see directly that this being is eternal? How? Really how?
That is impossible. Does that being say it is eternal? And is it therefor true (Maha Brahma) No…there is no reason to belief one can have direct knowledge of an eternal being, eternal soul or eternal Atman. Eternal is just a category of thought . I belief it cannot be an object of direct knowledge.
The same with all those views as: the world is eternal, not eternal, it is limitless, limited, the tathatagata exist after death etc. There is no direct knowledge of it. It are only thoughts, opinions, conclusions, only based on reasoning. The Buddha taught this is not conducive to attend to.
Regarding the existence of heaven and hells, all religions, i belief, advance some kind of afterlife. I think this can be established in direct knowlegde with the heavenly eye.
The real problem of delusion is, i find, that people start claiming knowledge they do not really have. That causes many problems, many conflicts because only craving leads them. It is all craving-and conceit driven and not by truthfulness. I feel that is the main message of Buddha about views. This is all self and other deception. Claiming to be a knowledge master while one is just a philospher.
Many people literally translate what they experience according their wishes. Example: one has an experience of overwhelming love. And because one is a Christian, this experience becomes a personal meeting with God. Now one knows God. That kind of translations. It is not really truthful because what one has really experienced becomes something else.
