You may be uncomfortable with the idea that God uses a section of the firmament as a movable platform like a giant cosmic surfboard. We get it, this is a deep end and we went off it. It's what we do.
A Pavement of Sapphire Stone
Riding the Heavens
God and the heavenly host may visit the Earth on a section of the firmament, described in Exodus 24:10 as a paved work of sapphire stone. This gives us a Biblical basis for the Silver Surfer.
Foundations of Sapphires
The firmament was originally composed of many more layers than it is now. One layer in the midst transformed into something like obsidian, completely black, and melted causing the inner layers to separate.
The Brightness of the Firmament
The creation of gravity and formation of the firmament was to establish a place, heaven, where God would dwell in perpetual light because the firmament is bright like the sun, as we see from Daniel.

Given that the apostle Paul specifically refers to something called the third heaven it's not a stretch to conclude that there must also be a first and a second heaven. We need to know what they are.
The Star of Bethlehem
As far-fetched as it may seem that the angelic host visited Bethlehem on the night of Jesus birth riding on a section of the brightly shining crystalline firmament, we shouldn't be surprised.
September 24th
It's possible that a section of the Firmament, a sphere of rigid crystal on the edge of space, may have been used to transport the host of Heaven to Earth for the birth of Jesus.
