the burden of proof lies with the believer. if you believe strongly in something, you should be able to prove it. or be willing to accept the fact that others may not believe in what you can't prove, without feeling offended or challenged.
I am not offended with your lack of faith. It is not my business what you believe in or do not believe. Atheists always demand from believers to prove existence of a God, atheists should be able to prove non existence of Allah too. But I have many other related questions , if you like to answer those that is fine if you do not that is fine too.
