Where did the universe come from? Atheistic origin science has no answer.

Others have covered the problems with what you say the Bible says. I'll take on the claim that no scientist in the five and six hundreds following the OT knew the earth was round:

The Greeks formulated the idea that the earth was spherical in the 6th to 5th centuries B.C.

Plato simply takes the spherical nature of the earth for grant it. Aristole provides reasons for thinking it so:

By about 240 BC the Greeks had done better than observe the earth is round, Eratosthenes, estimated Earth's circumference with an error of only about 5-15%. He used trigonometry, not scripture.

The Greeks didn't keep this knowledge to themselves either. Pliny (23-79 AD) and Cicero (106-47 BC) both refer to the round earth as a matter of common knowledge.

Nor is this only a Western bit on knowledge:

It is a myth that most people thought the earth was flat at the time of Columbus. Columbus proposed that the earth was smaller than previously thought. He was wrong, and if North and South America hadn't been in the way, he'd have died trying to reach India.

Except that the book of Isaiah was written in the 7th century B.C., which makes your point kinda moot.

Actually no. Isaiah was not written in the 600s B.C.E. Most scholars accept that the first 39 chapters in Isaiah are based on Isaiah ben Amoz, who lived in the Kingdom of Judah during the reigns of four kings from the mid to late 8th century BCE. However, he did not record the book in the 700s. It was probably actually written in the 500s by others.

Verse 40:22 (the verse in question) is not even based on Isaiah be Amoz and was written at the earliest during the Babylonian captivity, in the 500s, but more likely later yet after the exile had ended. http://en.wikipedia.org/wiki/Book_of_Isaiah

Believer's date, which I addressed, is fairly accurate. Yours is not.
