Ancient triangular structures prove the earth is stationary and level

Ps 104:1-9

1 O LORD my God, You are very great:
You are clothed with honor and majesty,

2 Who cover Yourself with light as with a garment,
Who stretch out the heavens like a curtain.

3 He lays the beams of His upper chambers in the waters,
Who makes the clouds His chariot,
Who walks on the wings of the wind,

4 Who makes His angels spirits,
His ministers a flame of fire.

5 You who laid the foundations of the earth,
So that it should not be moved forever,

6 You covered it with the deep as with a garment;
The waters stood above the mountains.

7 At Your rebuke they fled;
At the voice of Your thunder they hastened away.

8 They went up over the mountains;
They went down into the valleys,
To the place which You founded for them.

9 You have set a boundary that they may not pass over,
That they may not return to cover the earth.
