Is there objective Truth?

[Arkilogue]

Did I say Universe? Or did I say "all"? Can you envisage a scenario where those two are not coincident? I can.
Can we, humans, affirm that all that exists is contained in this Universe? NO."

So can I: There are infinite universes and more being created and they are all dominated by voided space with very little matter. Between the universes and above/below them is saturated space dominated by all matter.

The Universe IS all. Lol
Considering space time is expanding into NO space and NO time, it's safe to say there is no existence outside our universe. If you want to be a rebel and refuse to follow the evidence where it leads that's fine, but don't try and call me unreasonable.

That's an unnecessary assumption.

" Ultimately, you can't claim anything about any beginning, because you don't know if there was one... you can only claim something about this Universe...."

Well we can have the upmost confidence this universe had a begining believing in an infinite regress of causality is more of a leap of faith than beleiving in an uncaused first cause. That everything just exists with no explanation is more of a stretch then magic

The time-space (so that stuff may move/change and make "time") had a beginning....the stuff flung into motion had no beginning according to the 1st law of thermo dynamics. The "beginning of time" is the beginning of motion not the beginning of stuff.

These are human paradox's. You cannot try to comprehend God when you yourself think in a 3D box. We can however deduce, for example laws that come forth from said first cause could not possibly be bound by them.

You certainly can try and if you don't you'll never succeed. I dance on a tesseract.

Leading us to believe in a material-less, tim-less, space-less cause.

Again, an unnecessary assumption. The least special pleading case is that a pre-existent something changed phase/state and what resulted is the universe we find ourselves in. The "beginning" (of a universe) is the phase change.
