[DC] What is Darkseid's age?

Like, how old IS he exactly?

Darkseid IS.

We know he's younger than the multiverse, but that's it. The Fourth World (Apokalips and New Genesis) is 4.8 billion years old, so at the oldest he's 4.8 billion years old. Is he older? Possibly, we don't know how long that Uxas (the name he had before he became Darkseid) was around.
