What proof and evidence is there for "atheism" to be accurate and correct?

[Phish]

Moses followed god words for 40 years(not sure if i got this right but they needed a lot of time to get to that jew country) if god is so good he would lead them to that "new land" in few days or in a year not 40 years how is this love for your creation,and in the end Moses even isn't let to go in that "land" because he didnt tapped the rock 3 times he only tapped it 2 times,how more stupid can you even get to believe this shit?

Come on fine believe in this shit but leave us alone and live your fucking life and stop worrying about death there is only one life and this is now so get off your computer have a little faith and live every single minute like its your last

And the followers of Moses, the ones who were supposed to have directly witnessed the miracles and been personally helped by yahweh couldn't stand him. Soon as Moses turned his back they started worshiping a different god. The golden calf.
Now this seems odd behaviour for people who were supposed to have had absolute proof of Yahwehs power, moses killed 3000 of them for this little transgression.
Seems to me that the miracles the bible describes weren't as convincing as advertised.
