There may be no argument for God which will convince the hardcore atheist.
What you call the hardcore atheist is what I call the critically thinking strict empiricist. Such a person has standards for belief which the hardcore theist can't meet. The theist lacks a criterion for his god belief better than that it seems or feels right.
maybe one day you will open your heart, and you will know
Open your heart is code for shutting down critical thought and beginning to think like the theist, admitting ideas into one's belief set for no better reason than the theist has. Sure, if he cripples his defenses against acquiring false and unfalsifiable beliefs, that can happen.
Hey, maybe someday you'll soften YOUR heart and start believing in vampires.
God, I’m sure, can accomplish that for you.
Only if it exists. So far, no word from your god or any of the others.
The biggest argument against naturalism, that I can think of, involves humans. If we assume, we as humans are a product of natural selection, which is consistent with naturalism and natural forces, why are we, as humans, not limited to only what can be sensed by our naturally formed five senses? Science would be very primitive if we did not have science tools, that extend our senses.
Your argument against naturalism is the existence human invention? And that's your best argument?
Incidentally, we still use only native senses even with our machines. A Geiger counter turns radioactivity into clicks that can be heard, but we're still using our native sense of hearing. Space telescopes create images for eyes even in frequencies outside of the visible spectrum. Your phone lets you know when it has got something for you by making sound or vibrating in your pocket.
Also, there are more than five senses. You probably mean the exteroceptors - those which senses what is on or near the body. What is commonly called touch is actually many senses including tickle, pressure, vibration, and temperature. There are also sensors that detect the position and movement of the limbs and body, detectors in the viscera that manifest as things like heartburn and needing to urinate, and chemical sensors such as those that tell us that we need water or our blood oxygen level is too low.
Our natural senses have not kept up in terms of the naturalism that is defined by science.
Evolution hasn't proceeded faster than it has, so for you, that's an argument for a god or gods?
one is required to have faith in what cannot be seen, touched, tasted, heard or smelled.
One should not believe ideas that cannot be confirmed by the senses (empirically). It's not essential that one believe by faith, by which I mean insufficiently justified belief (justified belief is also called faith, but that's a different word spelled and pronounced the same, i.e., a homonym that is both a homograph and a homophone). One can train himself to avoid that kind of thinking.
