I believe in Allah because one of the tiniest of creation which is atom has the most complex system for me not to believe the world came by chance. If God did not exist how does water freeze from above and not below? who gave this vital law of physics? Another thing to add woudnt a God want to demonstrate people of his existence and communicate with them and give out laws to be closer to him?
explain to me because I'm failing to understand what's faulty in what I said.
It's circular reasoning. You assume that complexity implies a creator , then you begin describing the complexity of systems and then again claim god exists.
Complexity does not have to be divine, a key example is the randomness of flipping a coin. Due to the chaotic nature of the world its position in the end cannot be ascertained to 100% certainty.
Now let's say I threw 1000 thousand coins on the ground.There is a chance that the coins form the message "I am God". Thus pure randomness could form a message, new information arriving from nothing.
Another reason your premise is wrong is due to the insistence on a living being to have created the universe. God must've come from something, if he hasn't then why couldn't the universe also come from nothing?
Hence you dont apply the rigirous limitations you have setup for the universe on God.
Finally, a God existing does not mean Islam is correct. Islam is riddled with obvious scientific innacuracies and a 7th century Arabian world view of the universe.
