But 
where does Scripture say that thew firmament is solid or a dome?  The verse you keep quoting, Job 37:18, mentions the sky, not the firmament.  Why should I watch a video?  Why can you not just quote a verse that teaches that the firmament is a solid dome?  I mentioned before that I have looked at every verse in the bible that mentions the word "firmament."  Here they are:
Ge 1:6  Then God said,  Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. 
Ge 1:7  Thus God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; and it was so.
Ge 1:8  And God called the firmament Heaven. So the evening and the morning were the second day.
Ge 1:14  Then God said,  Let there be lights in the firmament of the heavens to divide the day from the night; and let them be for signs and seasons, and for days and years;
Ge 1:15   and let them be for lights in the firmament of the heavens to give light on the earth ; and it was so.
Ge 1:17  God set them in the firmament of the heavens to give light on the earth,
Ge 1:20  Then God said,  Let the waters abound with an abundance of living creatures, and let birds fly above the earth across the face of the firmament of the heavens. 
Ps 19:1   To the Chief Musician. A Psalm of David.  The heavens declare the glory of God; And the firmament shows His handiwork.
Ps 150:1  Praise the LORD! Praise God in His sanctuary; Praise Him in His mighty firmament!
Eze 1:22  The likeness of the firmament above the heads of the living creatures [was] like the color of an awesome crystal, stretched out over their heads.
Eze 1:23  And under the firmament their wings spread out]straight, one toward another. Each one had two which covered one side, and each one had two which covered the other side of the body.
Eze 1:25  A voice came from above the firmament that [was] over their heads; whenever they stood, they let down their wings.
Eze 1:26  And above the firmament over their heads was the likeness of a throne, in appearance like a sapphire stone; on the likeness of the throne [was] a likeness with the appearance of a man high above it.
Eze 10:1  And I looked, and there in the firmament that was above the head of the cherubim, there appeared something like a sapphire stone, having the appearance of the likeness of a throne.
Da 12:3  Those who are wise shall shine Like the brightness of the firmament, And those who turn many to righteousness Like the stars forever
Not one of those verse mentions the firmament being solid.  I know you have sometimes quoted Ezekiel 1:22, which mentions awesome crystal, but that is talking of the  
colour, not the solidity of the firmament.
