Ok, there would be wars, but for how long? Without religion, they may have well ended centuries ago.

No, you need a lesson in history. The majority of all wars in history had little or nothing to with religion at all.
The major causes of war are:
- Independence
- Land
- Economic gain
- Civil Disturbances
There's really only The European Wars of Religion, the Crusades, and the Reconquista religious war. World War I and II two of the biggest wars were not religious wars.
It is pretty difficult to fight in the name of "Jesus" or "Buddha" but easy to fight in the name of "Mohommad" or "God" (old testament).
Here are some wars that had nothing or very very very little to do with
religion:
