All the abrahamic religions have a man for God's messenger. Because the inventors of these religions were pure politicians and they could not convince any people then, who used to worship female God (nature's powers) that God is male, which would help in their upcoming politics of patriarchy and capitalism. So, they convinced people of a God's messenger, a male, and killed all the people who didn't believe their story. Then later as time passed, convincing the next generations that God is male became more easy because of the gender of the messiah and because the people from before the invention of these religions were all dead, and also because these people infiltrated the society with their dominance based culture and politics and also edited the "holy books" several times by then to fit their narrative.
