And even as they did not like to retain the Lord in their knowledge, the Lord gave them over to a reprobate mind, to do those things which are not convenient; Rom 1:28 After falling so low in the downward spiral, a person eventually gets to the point where they are unreachable by the Truth.      Such end up with a Reprobate Mind because they knowingly and willfully reject the Truth, Jesus Christ, There are two major results of this:    → they do things which are self-destructive    → the Holy Spirit ceases to draw them.

And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: 2Th 2:8 The wicked beast, the Anti Christ will appear for a short time.      Christ will return to destroy and consume him in the Day Of Wrath,

Even him, whose coming is after the working of Satan with all power and signs and lying wonders, 2Th 2:9 Satan is the force behind the beast, the Anti Christ, enabling him to do signs and lying wonders.

And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. 2Th 2:10 The beast will exercise influence and power over all those who have received his mark, name or number.      Those in his power did not receive a Love Of The Truth through Christ Jesus and so were deceived,

And for this cause the Lord shall send them strong delusion, that they should believe a lie: 2Th 2:11 Not having a Love Of The Truth resulted in them falling under the power of Strong Delusion to believe the lie of the Anti Christ.

That they all might be damned who believed not the truth, but had pleasure in unrighteousness. 2Th 2:12 Damnation is the end result of rejection of the Truth, believing the lie and worshipping unrighteous pleasure.

Cosmology is a branch of astronomy that involves the origin and evolution of the universe.   

The Bible tells us how God created the heavens and the earth in the first three chapters of Genesis.   

Why would an area of study come about to discover how the heavens and the earth came about?   
Because they did not retain God in their knowledge.   They did not believe His Word.   

Since it is impossible to go back in time and observe the creation, the only thing the cosmologist can do is to construct myths about what happen.
