Every thing on this world that has bodies and brains come in both females and males. So why are,many Religions male God as no females?

It depends on the religion. Pantheons will have an equal number of gods and goddesses, or at least an even distribution of important responsibility. Monotheistic religions always seem to worship a male deity

That is why he is God. Everything else is creation. Why is there males and females on earth? It's so they multiple. God is one. John 3:16-17.
