Because it's difficult for a Deity which is no more than the figment of a paedophile's crazed imagination to do anything. The fact that millions of hysterical people, mainly sweaty Arabs worship this fictional character doesn't make him/her any more real than all the other man made Gods. This question could also include, why do millions of so called Muslim refugees have to travel through oil rich Islamic States to seek solace in the countries of Christendom. Even the thickest Muslims with their illusory God must wonder why Allah expects the, equally imaginary Christian God to do his dirty work.

Probably to start World War III. He knows how to rile up the Muslims.

Becuase Isrealis are fucking badass. Also, because the female athletes are basically not allowed to go anywhere without the permission of their hubbies.

Training and determination won Olympic Gold, not any Flying Spaghetti Monster.

Well, Judas got 30 pieces of silver a couple centuries ago. Maybe one piece of gold costs a little less than all that silver again? God's got to hold to a budget too you know.
