Why would they lie about the design of the earth realm?

So many reasons, but understanding where you live frees your mind and allows you to act as a landowner if you know the True Owner of earth.

The King of Glory and His Kingdom

1 ¶ A Psalm of David.

The earth is the LORD’s, and all its fullness,
The world and those who dwell therein.

2 For He has founded it upon the seas,
And established it upon the waters.

3 Who may ascend into the hill of the LORD?
Or who may stand in His holy place?

4 He who has clean hands and a pure heart,
Who has not lifted up his soul to an idol,
Nor sworn deceitfully.

5 He shall receive blessing from the LORD,
And righteousness from the God of his salvation.

6 This is Jacob, the generation of those who seek Him,
Who seek Your face. Selah

7 Lift up your heads, O you gates!
And be lifted up, you everlasting doors!
And the King of glory shall come in.

8 Who is this King of glory?
The LORD strong and mighty,
The LORD mighty in battle.

9 Lift up your heads, O you gates!
Lift up, you everlasting doors!
And the King of glory shall come in.

10 Who is this King of glory?
The LORD of hosts,
He is the King of glory. Selah
