I find it inconsistent, that modern atheists deny Existent God in favor of Non-existent one because they accept everything, which is not the Existing God: e.g., the satan, freewill, love, hope, and soul.
Really?
I'm not technically an atheist, but I'm an unbeliever. I admit the existence of any number of imaginary gods, but there isn't even a definition of a real god such that if we found a real candidate we could tell whether it was God, or a god, or not.
Nor is there a definition of a real supernatural state or a real supernatural being that would allow us to determine whether any real thing is such a being or in such a state. That rules out any real Satan and any real soul.
Love however is a physical state of attraction explained by evolution and biology, the advantage of pair-bonding through hormonal responses, not least with oxytocin. Love is a particular set of real brainstates ie love is real.
As is hope, simply part of the evolved ability of the brain to consider future possibilities and to have emotional responses to those possibilities.
As for freewill, yes we all know of occasions when we can decide between A and B independently of external coercion.
However, we know of no instances where the brain can make non-random decisions dependently of its evolved and physical decision-making processes.
And believe it or not, but Physics can be reduced to mathematics in the way down to Absolute Solipsism: "the mathematical universe hypothesis" (Wikipedia).
I don't think the universe is mathematics. That would mean that without humans the universe doesn't exist, since maths is entirely conceptual, and humans are the only critters we know of that do maths that's at all complex.
