The paradox is that "endlessness" is beyond human logic, but at the same time our logic tells us existence of forces & time must be endless.
The mythology of "gods" that humans have written may be a real message, or may be complete baloney, but the conclusion of human logic has to be: there is "something", a force, a law of nature, a god, something that is endless without a doubt, but we can not and may never understand.
It's possible that when we die we will find out, or it's also possible that we are an accidental germ in this universe that stops living and never finds out what's really going on with our endless universe.
The way I would imagine something endless is like a circle. A circle has no beginning or end, but it has points on it.
