Do you beleive in god

In my opinion god isnt real now thats just my opinion i think when you die it's like eternal nothingness maybe like sleeping but you dont dream and i think maybe churches and bibles were made up because humans are naturaly scared of death to give us comfort and less fear of death its like if a spider runs along you squash you dont say its a way to heaven its dead game over we all get a little show on the planet but thats it no more. i'd love to be wrong but i cant see it, what do you think
