"truth doesn't exist" -- except for that truth statement you just made? If no truth can exist, then why are you making a truth statement?
Truth does exist. And the ultimate truth is Christ. Yes, those words ring as ignorance to most, but just like we are forced to reckon with gravity and the laws of physics, we all will one day reckon with the ultimate truth.
But it is not my job to compel anyone to believe this. I just find it fascinating that non-believers will believe in magic, ghosts, simulations, aliens, evolution, but that a Creator that exists outside of time, space, and matter created this universe? Nah, that's ignorant religious thinking.
