I will prove to you that God exists

[The Architect Of Fate]

You're free to say you lack belief in your strawman of Atheism, though that won't shift the burden of proof onto the Atheists in anyway. Until you demonstrate the existence of god, atheists have a sound position and don't have to come up with alternative explanations to  God nor does  not accepting  a god mean they are pushing for any other positive position or explanation. This attempt sad at burden-shifting or trying to give your position de-facto legitimacy fails.
