How much pain can atheists withstand ?

[Angrboda]

YOU claim a god exists, so the burden of proof is on you.

I provided my proof : 

all experience show that only personal agents produce things. It takes work to accomplish things. A fortiori, it took some agent's work to bring about this universe and all it contains

This is not deductive proof (it's not analytic), it's analogical

Analogical arguments don't prove or demonstrate things. They are useful for illustration or pedagogy, nothing more. The general consensus is that the argument from design is unsuccessful, for numerous reasons that we can get into if you like. Your presentation of it isn't particularly skillful, much less persuasive. Can you show that it is necessary for snowflakes to have been designed? Can you show that it is necessary for life to have been designed? Can you show that it is necessary for the universe to have been designed? Can you show the universe was even created? (Big tip: no you can't)
