You've misunderstood. I was referring to the so-called Islamic Golden Age.

Nothing to do with "miracles in the Qur'an" if that's what you mean. I don't believe in any of that stuff anyway. (Using often vague verses to argue for scientific principles that were discovered centuries later, but those verses often weren't traditionally interpreted that way until science came up with those ideas. Like how it's currently believed the universe is expanding, and some Muslims use a single verse to argue that was stated in the Qur'an, but the language of that verse is pretty vague and open to interpretation. Also scientific consensus can change, and then what happens to those verses? If believers want to try and match verses with new scientific understanding, that's up to them, but it's risky in my opinion, (because scientific understanding is always evolving), and also, I think, unnecessary. You don't need to prove any scientific "miracles" to believe in your faith. You can do that anyway.)
Islam has existed for about 1400 years. But it didn't come "last". Several other major religions/religious movements have been "founded" since then (Bahá’í Faith, Druze, Sikhism, Mormonism/LDS, Hare Krishna, for example). As for "copying" everyone, yes it draws heavily on Judeo-Christian beliefs, just as Christianity draws heavily on Judaism (and "copied" it?).
