So you when to hell now what.

Every person should be able to state at five reasons for the universe’s existence’s. Amazingly, the atheists can’t even state one…

I can.
But the universe has only one reason to exist:

It's all in the plan.
A matter of fine tuning.
The physical constants are delicately balanced to produce the primordial H and a little He which coalesced into stars.
The first generation stars went nova after making C and N and I and all the elements necessary for the execution of the plan.  
This mixture formed another generation of stars with planets one of which is in just the right location for organic life to emerge.
And life did emerge exactly according to the plan and began to evolve.
And humans domesticated hopps and barley according to the plan.
And eventually, after billions of years, evolution produced Willis Carrier, the inventor of mechanical refrigeration.
And, executing the culmination of the plan, I just went to the refrigerator and got another beer.
Which is the reason for the existence of the universe.
