Why do so many people worship the Abrahamic God?

Other than the God of Abraham, Isaac, and Jacob, as well as the Father of our Lord, Jesus Christ, there is no other God worthy of our worship. I don't know what you have read, but it sounds suspect. Blessings on your journey.

Because, over the centuries, it's been one of the least falsifiable gods, there's supposedly only one of them which simplifies things, and he's the concept of god that was used to conquer Europe then later the Americas.

It is due to many eyewitness acts of the Abrahamic God in ancient times.

Childhood indoctrination. That's why. As to why it is more widespread than other religions? The conqueror's of the last few centuries were Christians, so they spread their beliefs to the lands they took over or otherwise strongly influenced.

Mostly in the Northern Hemisphere, since the whole deal is based on astrology from those watching the skies in the northern hemisphere. You were raised as a Christian, and so it is passed on from generation to generation, the original sin. That would be the lies told us about life and about God.

To most people the GAWD thing is just another word for the memories of their parents at an early age.

It's not real deep. But people feel they need to be "close" to something like that and swallow the stupid shared lies.

Because he exists! I guess people used to worship Zeus and Athena as a cultural thing and still worship Krishna and Shiva.

God is one. He is the supreme person. God loves humankind.

that's why all Atheists hate God

because jehovah is god
