Well, I agree with you, but he (Moses) did appear at Transfiguration.

Now I haven't the slightest idea what that means, but...

It's a mystery to me too. Best idea that comes to my mind is that Eternity and time met on that mountaintop that day. Jesus appeared to the three disciples similar to how He appeared to John who recorded (wrote) the Revelation of Jesus Christ.

Perhaps some comparison of notes took place? Some information was passed to Jesus or the other way around?

Definitely a Heavenly vision by the three disciples who had no idea what to do next. (Wanna build a temple or place a plaque or do something else here?, asked the dazed and fazed Peter.)

Oh, and the Father was present too; His voice was heard setting Peter straight.

Moses and Elijah appeared with Jesus at the Transfiguration. They represented the Law and the Prophets, of which Jesus was the fulfillment.

Peter was ready to set up tents, booths, as was the custom for visitors, ie Moses and Elijah.
