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

So how can a book that was written 500Bc state that the world is a "globe" and "spherical" But this was only believed 100s of years later when it was mentioned by scientists after years of saying the world was flat.

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.

Pythagoras (6th century BC) was among those said to have originated the idea, but this may reflect the ancient Greek practice of ascribing every discovery to one or another of their ancient wise men. Some idea of the sphericity of the Earth seems to have been known to both Parmenides and Empedocles in the 5th century BC,and although the idea cannot reliably be ascribed to Pythagoras, it may, nevertheless have been formulated in the Pythagorean school in the 5th century BC although some disagree.[14] After the 5th century BC, no Greek writer of repute thought the world was anything but round.

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

Aristotle provided physical and observational arguments supporting the idea of a spherical Earth:

Every portion of the Earth tends toward the center until by compression and convergence they form a sphere.
Travelers going south see southern constellations rise higher above the horizon; and
The shadow of Earth on the Moon during a lunar eclipse is round.

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:

The works of the classical Indian astronomer and mathematician, Aryabhatta (476-550 AD), deal with the sphericity of the Earth and the motion of the planets. The final two parts of his Sanskrit magnum opus, the Aryabhatiya, which were named the Kalakriya ("reckoning of time") and the Gol ("sphere"), state that the Earth is spherical and that its circumference is 4,967 yojanas. In modern units this is 39,968 km (24,835 mi), close to the current equatorial value of 40,075 km (24,901 mi).

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.
