This is the trick of Shaytaan,let me tell you something,go back to the roots,forget these anti islamic sites,etc and start with basics and sunnahs, like wudhu before bed,etc,etc.
As for the second,how do you know whats likely from God and what isnt? Its only God who bestowed everything upon you.
As for the third,These arent comfort zones and excuses,if these were excuses,we would have no support to back our argument,no source,nothing,
4th. If God was imaginary for the comfort of mind,then he wouldnt afflict us with trials,he wouldnt have revealed a book,he wouldnt even have created us. Because he didnt exist according to your thought,if it was true that God was imaginary then everything should be random and we shouldnt have a perfect orbit.
I think its time you stop visiting these anti-Islamic sites and wasting hours over them,you're weak in faith,Zakir,my advice is,get out of the internet for a bit and start going to the mosque and ask your Imam these things.
Shaytaan will slither into your mind with disgustful thoughts the more you keep going into these sites
