Turns out he is correct.

The steps temple was built by Joseph and was primarily a grain storage facility.
This assumes it was originally built as a solid structure rather than as an empty structure which was re-purposed. I’m not trying to support his statement, but it is not exactly extra terrestrial level thinking either. I have friends in Vermont who are living in a three level home that used to be a church. Things can be changed after they are initially built. People can scoff, but I am not sure that because we find a structure purposed one way, it was built for that exact purpose, especially one that was built so long ago. And this is exactly the bait we always rise to. It’s a shoulder shrug at best.
