Human is a name given to our species, meaning God nor any of the spiritual beings falls under that category. Also, there are a few scholars who debate whether God made us in his image or if it was that He is merely an anthropomorphic Deity. Ancient Greeks gave many human attributes to their gods, and since Romans copied/adapted most of the Greek Culture to theirs (like naming Zeus Jupiter, Ares Mars, Venus Aphrodite, Poseidon Neptune....and so on), and since most Christianity took a boost in Rome becoming now what we know as Roman Catholicism, it would only be natural to think that the God displays many human attributes like He does today.God is neither. He is the light, most holy, pure, etc. He made us in His image. That doesn't mean he is human.
I think calling them an idiot is a bit much. There are female images of God in the bible. We talked about these in my concepts of God class when I was in college. I think that the masculine image of God is more popular due to culture. We talked about how culture influences religion as much as religion influences culture.If we're talking the Christian God and not just a generic "god" then God is a he. That's obvious to anyone. Anyone who thinks otherwise yet still adheres to the Christian doctrine is an idiot. And yeah, there's the whole genderless route, except that Jesus Christ was a male.
First hand account of God, illustrated in his trendy pink robe-So God created man in his own image, in the image of God he created him; male and female he created them. 28 And God blessed them, and God said to them, "Be fruitful and multiply, and fill the earth and subdue it; and have dominion over the fish of the sea and over the birds of the air and over every living thing that moves upon the earth." 29 And God said, "Behold, I have given you every plant yielding seed which is upon the face of all the earth, and every tree with seed in its fruit; you shall have them for food. 30 And to every beast of the earth, and to every bird of the air, and to everything that creeps on the earth, everything that has the breath of life, I have given every green plant for food." And it was so. 31 And God saw everything that he had made, and behold, it was very good.
