Don’t work that way.
Some of that truth comes from science, some from logic and some from hard physical fact. Just because it shows your “faith” to be not factual but simple “belief” does not make those scientists, thinkers and fact finders liars, it means that you have a belief.
To be atheist you simply do not need to lean on a god crutch, any god crutch. To be a liar you need to either deliberately or compulsively distort the truth, as christians are so good at doing.
To call those who know through physical evidence that your belief is not factual liars is just a pathetic admission that you are clueless godbot of little intelligence.
And selectively making BS up claiming that death does not apply to you because you believe in a god is the wishful thinking of clueless a godbot of little intelligence and no evidence to confirm it.
What this boils down to is your nasty, incredulous and ignorant attitude to anyone who does not follow your exact delusion. A delusion based on NOTHING but bronze age and iron age books with NO actual evidence to back up that delusion.
And you call people, who see the physical evidence liars? How do you sleep at night?
Atheism and Theism are both belief system.
No one can defeat God, except they can defeat death.
