if God is created, it means there is someone created God! and this will never end if u ask about who creates who. God is the creator of everything. God gave his cretions esp human the attribute to think and free-wills. God let scientists to discover things that he created. Scientist discovers the things that God created, God himself knows everything but it is the scientist that just knew about it. Look at my above comment about the 'fire creation' and think about it. We Muslims knew about green leaves as being fuels 1400years ago. Try to talk about this verse and try find any contradiction, you wouldnt!
