What would a 'Creator' so capable want with such a universe?
Wrong question. What you should be asking yourself is what would the universe be doing here without a Creator?
Who created the creator?
No one created Him. Our universe, and everything in it, had a beginning. God is Spirit. I don't know exactly what that is, but it is something greater than and apart from our physical universe. So He has no beginning. I realize that it's difficult to wrap your mind around such a concept, but the alternative is to believe that the universe created itself. That's what you believe, isn't it? That it just exists for no reason at all? How is that any more logical than believing in a Creator?
Because there are so many more possibilities you haven't even considered. You are correct it is hard to wrap your brain around this, but there was time and space before our universe was created. Think of us as one bubble in a lava lamp

Your universe is just one of a google of universes in an infinite cosmos. You seem to be putting god and/or the cosmos in a box my friend. God isn't eternal and it isn't GOD that has no beginning and no end. The cosmos do.
You can not disagree because even if there is a god and even if he did live forever, he had to live somewhere. And if there is a god, which there probably is not, but if there is, he is a lot older than 13.5 billion years old, am I right?
What created that one little bubble in the bottom right of that lava lamp? To the things that live in that bubble, they can not see the other bubbles, just like you can not see other universes. Not yet anyways.
Poppycock! There is absolutely no evidence of other universes. Also, have you ever heard of the LAW of cause and effect? Everything that happens is the result of something causing it to happen. We live in a single universe. It had a beginning. Something caused it to exist. Since you cannot have a infinite regression of causes, there had to be a primal cause that was itself uncaused. The only definition that fits that primal cause is God.
See how close minded you are to other possibilities? When the fact is, there is no evidence for your god either.
Yes, our universe might have been caused because another one collapsed. Ever hear of black holes? Do you know what's on the other side?
What caused god? If god can be eternal and causeless, why can't the cosmos?
Stop making bad arguments
God created/caused the universe.
The First Cause Argument, or
Cosmological Argument [
2], is
internally contradictoryand raises the following questions: Who or what created god?, Why should a hypothetical ācauseā have any of the common attributes of a god?, Why is the ācauseā a specific god?, Why canāt the universe be causeless too? and, most importantly, Why rule out all other
possible explanations?
It is fundamentally a
āgod of the gapsā approach. Our current lack of understanding concerning the Universeās origins
does not automatically mean āgodā holds any explanatory value. Metaphysical and theistic speculation
are not immediately justified or correct simply because we lack a comprehensive scientific model. Uncertainty is the most
valid position and one can honestly say āWe just donāt know yetā.
The argument ignores the fact that our everyday understanding of causality has been arrived at via
a posteriori inductive reasoning ā which means it might not apply to everything. Time, for instance, appears to have begun with the Big Bang, so there might not have been any ācauseā for the Universe to be an āeffectā of since there was probably
no time for a ācauseā to exist in. Applying concepts like time and causality to the Big Bang might be comparable to asking āWhat is north of the North Pole?ā ā ultimately nonsensical and incoherent. Furthermore, even if causality could be established it would not immediately imply the existence of a god, much less any
particular one, as the properties and nature of the ācauseā could forever remain a mystery or be
naturalistic.
In fact, something can come from nothing and we are able to
observe it in the form of
virtual particles and
quantum vacuum fluctuations. They explain why the early universe lacked uniformity and provided the seeds for the
emergence of structure [
2][
3]. These quantum phenomena are also causeless in the sense that they are objectively and irreducibly
random, a fact confirmed by tests of
non-local realism and
Bellās Theorem.
Note 1: Theists often state āGod is outside of timeā. This claim does not actually make their speculation correct. Instead, it brings with it a whole
host of problems and may be immediately dismissed as being without basis and a type fallacy known as
special pleading.
Number 8. We've already debunked all your arguments.
Why there is no god
