That is not true. God Exists. even if there is no proof. how do you think we exist today? we were made to worship god. this world was created. in 4 days, the galaxy, everything. within 4 days as said in the holy Quran. it might seem like billions of years for us. but it was only 4 days for god. I certainly cannot prove it to you. but it's called faith. when I was in my darkest time I prayed for God to help us. a miracle happened to us that changed our life. that's the only proof I have.
