Hi Steven, I don't know what the plans for Jesus' appearance will be and who will come first, we have heard different things at different times, but I think Jesus knows very well what is best for Him. Jesus has no fear and He knows exactly what to do in all circumstances.
As for Adam and Eve, I think they will be of fairly normal height, otherwise they could be seen as hostile aliens or whatever. It would cause a lot of problems if the were 8 to 10 feet, when traveling or staying in a place, they wouldn't fit in our cars, planes or in our buildings. But I think they certainly will not be short.
Remember, we heard that the incarnated Melchizedeks walked the streets and were indistinguishable from the average person, they didn't stand out. This probably also applies to Adam and Eve.
The same goes for Jesus. He has been in certain cities in the US walking among people on the streets, but if you accidentally bumped into Him, you wouldn't know it was Jesus. In the book 'Crown' Jesus says that He will be dressed like the modern businessman.
Thank you Steven, we’ll see one day!
Elise
