this is not a frivolous argument as you say, to you it may be but to many others it is very very critical in understanding many things especially when it comes to Creationism versus Evolution, I fully agree that we need to share the gospel more before Jesus returns and I do and we will be doing even more but this is a vital part of scriptures that needs to be addressed by people who know what they're talking about like Ken Ham and so many more, that's part of their calling so let them do what they are called to do and you do what you're called to do and I'll do what I'm called to do and things will work out
