These old arguments are known as “defeaters”. The best way to destroy them is on the atheists own terms.
I quit debating Atheists many years ago. I just give the Gospel story (if they will listen) and let it go at that, the rest is up to the Holy Spirit (planting the seed, as it were). In reading the Bible, you will never discover anything about Jesus “debating” the Gospel of Salvation … Mark 10:17-27 is a great example. If He didn’t choose to debate, who am I to do differently.
