Exactly. But then this is already "evidence" to them about the existence of God. Such people have no need to ponder that "If evolution is true then there's no meaning in life so that case is uninteresting, so therefore let's believe in God since then life is meaningful".

If God "speaks to you", you already "know" he exists. This was precisely what I tried to point out in my previous comment. If you have a method to pick out a particular God out of all possible Gods, then this method (or something related) can also be used to reject atheism directly. There's no need for the elaborate argument that I responded to.
