People have lots of reasons as to why they don't believe. The irony is that everyone is an atheist to some degree. If you believe in Jesus but not Allah then you lack belief in Allah, and I am sure that if you believe in Jesus you'd also lack belief in all other gods as well.
The only difference between an atheist and a theist is that we lack belief in one more god than the believer does.
