Why does most religion talk about their GOD being male? Especially Christains and Muslims. Is there a prominent female god that as big as the other two that I am missing?

Outside of Western religions there are plenty of other cool non-male deities. There's lots of pagan goddesses.

The only "feminine" or female deity that is maybe as well known as "God" would be like nature as it is often referred to as "mother" nature and in she/her. Though I'm not sure pantheists or other religions would refer to her strictly as a goddess.

Western religions talk about a male god because western societies are patriarchal; they need it to support a male-dominated societal structure.
