Oh goody, I thought experiment. OK I’m game.

Your point that scientific discovery is often preceded by unproven hypothesis, which may even be preceded by a philosophical idea, is well taken. Atomic theory, for example, has its roots in ancient Greek and Indian philosophy. But ideas and hypotheses have been shown to be incorrect as well. The existence of the luminiferous aether and the substance known as phlogiston are but two well known examples.

In that vein, the existence of a creator, or first cause, is perhaps the oldest human idea or hypothesis unsupported by evidence, apart from our own existence. With or without our observations, the universe, or nature, creates (or reforms) and destroys, and so far as we can tell is, as Anaximander of Maletis described it, boundless, apeiron.

The term “creator” implies an actor or intention. But to do this is to anthropomorphize nature itself! And if we have learned anything by now it should be that the height of human hubris is the anthropomorphization of all things unhuman.

Ten out of ten for your recent topics.

In the time line of the early universe it's posited that the higgs boson had yet to form.

Your contemplation of energy is perhaps best discussed in the context of the unfolding universe.

If the law of conservation of energy is correct then the idea of cause and effect may imply energy/particle energy always existing.

Particle and quantum physicists share your astonishment and wonderment.

Sometimes instead of "creator" and "created" it's simply creation, or natural consequences of various opposing forces producing something between them.

There are definitely things that currently exist or will exist, or previously existed that we know nothing about yet, but perhaps will be discovered and described, measured, and humans will see how these new discoveries fit into this big puzzle. We can only guess at the big picture until we have all the pieces, and the puzzle just keeps growing it seems.

The more we know, the more we realize we don't know. It's fascinating for sure! Fun to wonder about as well.

"If a tree falls in an uninhabited forest does it make a sound?"
Instead of writing all that above, a bit of reading would show you the basic thought has been around Forever.

You have managed to wander through the anthropic principle, determinism and the uncertainty principle then top it off with Paley's watch in the course one post.
Congratulations

You find a diamond, would you wonder who created it until you found out that it is carbon that has been under pressure that created the diamond. Nothing magical just cause and effect.

The idea of a creator is a human construct. It should be enough that we are here and someday we won't be. Enjoy life, be kind, and don't worry about the imaginings of others.

Please check your assumptions about the nature of existence and the nature of creation.

Science means knowledge and is all about our physical world: What we can sense. As technology improves we are developing sensors that "see" what we cannot, expanding our knowledge.
Science assumes everything is physical which I do disagree with. Science will never explain love/ empathy and why humans create; talking art here.
The arts eg fashion, paintings, visually appealing architecture, music etc etc are all non essential for human physical existence and yet we are surrounded by it. Example is fashion which has no real practical purpose in our lives. Logically there would be one way to create efficient dwellings, clothing etc.
Science seeks answers to our physical world, but there is something else I agree.

A favourite quote of mine is from Nicola Tesla with which I agree 100%. “The day science begins to study non-physical phenomena, it will make more progress in one decade than in all the previous centuries of its existence.”
We just have to develop sensors and start looking.

Re deity if we were "created", there has been zero interest in the creation by the creator so I call BS aka atheist. I tend to go Buddhist on this question, and accept "just is" instead eg forget the "why" and just get on with it. God's would not exist without humans as all other species don't care about gods. This strongly suggests to me that humanity created gods, not the other way around.
