The first hand account of the discussion that I saw as being discussed with Rav Moshe was a general science verse Talmud discussion. Not a what’s the Halacha with Talmudic recognized ידים מוכיחות discussion.
I can't answer for your account, but I personally discussed it with people who were part of that discussion who said they brought numerous scientific papers to discuss many aspects of this and R Moshe said that it was a waste for him to see it since it doesn't change the halacha.
Either way, this is guaranteed to be an endless discussion as it has been for about 13 years since I did all this research.
So I think I will just end it here.
