When God created the world, He intended for man to enjoy His entire universe. By Genesis chapter 4, man had become quite advanced. By Genesis eleven, man had very advanced engineering skills-—sadly used to rebel against his Creator.
There is no reason man would not have been allowed to fill the universe at some point, and God created a universe full of habitable planets.
The “second heaven” (outer space) is, however, now corrupted by the wickedness of the angels which kept not their first estate. Man will not be permitted to inhabit other planets until after the universe is purged after the Reign of the Savior, Jesus Christ, from David’s Throne.
A NEW heaven and a NEW earth will be created wherein will dwell righteousness.
What scientists are being allowed to see by way of telescopes and modern sensing equipment is just to remind man that all could have been his, were it not for man thinking he is smarter than God.
One day, the Regenerated saints of God, those who have been made new creatures in Christ, Sons of God, will enjoy a NEW heaven and a NEW earth, along with its far-flung reaches that glorify the Creator.
Sorry, Mr. Scientist, without repentance and faith in Jesus Christ, through your telescopes you merely see your own loss, and your own condemnation.
That explains the StarGate
