Thanks for such a great comment, and I disagree with none of it. I hit upon this issue in the post, but my main focus was to go over just one of the proposed answers to the paradox. The numbers seems so massive that there has to be many planets that have evolved intelligent life.

Again, this was just expanding upon one of the possible answers that has been made - and I have no idea which one is correct, but I also don't think we are going to know for sure for a long time yet.
