I don't see how that's so. Could you explain?

Some examples, the fine-tuning argument, the origin of everything, the immense order observable in nature and Mathematics. These aren't very easy to explain away as coming from some random chaos.

    And they say back then our universe
    Was an empty sea, until a silver fox
    And her cunning mate began to sing
    A song that became the world we know[1]

Having read that, did it become part of your worldview? Or did you dismiss it?

There is a mythical incident in the Old Testament where worshippers of Apis [0] are slaughtered by their brothers, who had freshly declared allegiance to Jehovah.

In general, the rise of monolatric religions in the Levant and Persia, religions where there are many deities but only one is worshipped, eventually turned to monotheism, where those other deities were derided and ignored. With this change, there were sweeping new priestly laws which insisted that it was blasphemous to worship those other deities.

You might be interested in a critical retelling of the Exodus [1] which puts in an effort to mention and understand the other deities which were worshipped around the time of these events.
