There is no proof that God is existed but there are trillions stars in the galaxy  and our sun is one of the star in the milky way galaxy and there are billion of trillions galaxies in the universe and there are trillions and trillions universes in the space beyond human being understanding which created themselves from nothing . God did not create the universe in 7 days and the universe is not only 6000 years old as the holly bible and the  Koran said.
The big bang could be proven to be right.
