Why Don't You Believe In God?

Hi,

I am a Christian, and I was just wondering why the non-believers on this board don't believe. Why don't they?

Protip human kind nearly 300,000
earth=3,650,000,000 years
universe=70,000,000,000 years*
Good created human as is own images and since humans has barely 300,000 years in the earth
The human god dosent exist and is not in any way the creator of the universe, earth or anything
