But the thought that "there has to be someone who created this, cause things don't just come by themselves, Nothing can come by itself"
Cuz lets say I write on a wall the letter "B" the letter would NEVER be there if I did not write it there, which makes me think that nothing can just 'come to existence' There has to be someone who put it there, created it etc.
But when it comes to Allah SWT, He simply exists, There is no 'before' Allah, cause Allah SWT is the First, He SWT is the self-existing one. The Self-Existing One - Al-Qayyum
This world runs by "cause and effect" which means that EVERYTHING that exist, must have a CAUSE for its existence, because without cause, it wouldn't be there.
Have you ever seen an essay being written without anyone doing anything? no.
Those are the rules which Allah SWT has placed, Allah is outside those rules.
I see those conditions for something to exist, as an 'attribute' of creation. The condition that for something to exist, it must have a cause, only applies to the creation.
Allah SWT is the sole creator, who placed the rules,The only one who can create.
I hope I got something right. lol.
