At Revelation 7:9, the great crowd is not seen as being in heaven. Their “standing before the throne” of God does not require them to be in heaven. They are simply in the sight of God. (Psalm 11:4) The fact that the great crowd, “which no man was able to number,” is not a heavenly class is shown by comparing its unspecified number with what is written at Revelation 7:4-8 and Revelation 14:1-4. There the number taken from the earth to heaven is revealed to be 144,000.
You're still not making any sense. The psalms did not refer to anyone being before the throne and hence it can't be used as comparison. The angels were stated to be around the throne. Are they on earth? No.
Jehovah is in his holy temple.+Jehovah’s throne is in the heavens.+His own eyes see, his watchful* eyes examine the sons of men.+
That is why they are before the throne of God, and they are rendering him sacred service day and night in his temple; and the One seated on the throne+ will spread his tent over them.+
The very scriptures you posted shows that they are in heaven. J is on his throne which is in heaven. The GC are before the throne in the temple. Hence, the GC are in heaven.
Anyway, I have no more time to debate this. Its just fiction after all...
