When materialists define consciousness as an emergent chemical process, the are affirming its existence, not denying it.
You have to accept that we ultimately have no explanation of why anything exists rather than nothing at all.
This is because the question itself is a fallacy, because it asserts that it is possible for the entity called "nothing" to exist, which is impossible by definition. As always, theists stand before the same problem, why does their god exist, rather than nothing? Victor Stenger explains it.

Einstein showed that mass and energy are equivalent, by E=mc2. So, if the universe started from "nothing," energy conservation would seem to have been violated by the creation of matter. Some energy from outside is apparently required.
However, our best estimate today is that the total energy of the universe is zero (within a small zero point energy that results from quantum fluctuations), with the positive energy of matter balanced by the negative potential energy of gravity. Since the total energy is zero, no energy was needed to produce the universe and the first law was not violated.
The second law of thermodynamics requires that the entropy, or disorder, of the universe must increase or at least stay constant with time. This would seem to imply that the universe started out in a greater state of order than it has today, and so must have been designed.
However, this argument holds only for a universe of constant volume. The maximum entropy of any object is that of a black hole of the same volume. In an expanding universe, the maximum allowable entropy of the universe is continually increasing, allowing more and more room for order to form as time goes by. If we extrapolate the big bang back to the earliest definable time, the so-called Planck time (10-43 second), we find that universe started out in a condition of maximum entropy -- total chaos. The universe had no order at the earliest definable instant. If there was a creator, it had nothing to create.
Note also that one cannot ask, much less answer, "What happened before the big bang?" Since no time earlier than the Planck time can be logically defined, the whole notion of time before the big bang is meaningless.
Furthermore, within the framework of Einstein's relativity, time is the fourth dimension of spacetime. Defining this fourth dimension as ict, where t is what you read on a clock, i = sqrt(-1), and c is the speed of light, the coordinates of time and space are interchangeable. In short, time is inextricably intertwined with space and came into being "when" or "where" (language is inadequate to mathematics here) spacetime came into being.
I have made the relevant parts of this quote bold. So it is clear that "before" the big bang or "cause" to the big bang are self-contradictory questions and therefore invalid points.
It is true that one might reject the idea of a necessary being and simply accept that the universe has no explanation for its existence - this approach was taken by David Hume. This is irrelevant to my point that evolution is not incompatible with theism.
Or one can simply point out that if you wish to postulate an arbitrary necessary being, you might as well hold that the universe is a necessary being -- we have at least seen that one. Yes, it has relevance for the incompatibility between evolution and theism, because it dethrones humanity in a cosmic perspective.
Is it not possible that I have considered the same facts and come to a different conclusion?
A lot of theists invoke this form of epistemological relativism when cornered. No, it is not possible that the same facts can lead to two different and incompatible conclusions.
Furthermore, I do not accept that it is possible to have "no ideology".
Also completely contradictory. If all statements and positions are skewed by the lens of personal ideology and therefore invalid, then this statement itself skewed by the lens of your personal ideology and therefore invalid. Invoking epistemological relativism will get you nowhere fast.
Science is an ideology as much as religion is.
This statement betrays a profound ignorance is why I doubt the validity of the credentials you claim you have. Science starts with the evidence, then uses logic, reason and empirical investigations to draw conclusions. Religion starts with their conclusions, then looks and see what evidence they can use to prop up their beliefs and which they have to deny in order to hold their beliefs as valid. This should be elementary with someone with a degree in mathematical physics.
For every point you have made, I have offered a valid counterpoint.
You have only stated that there are scientists who disagree, which is an appeal to authority.
I feel like I am arguing with a religious zealot here.
Likewise.
I am only arguing that evolution has not in itself disproved the existence of a creator.
But that is not what we mean by theism! By (Christian) theism (opposed to deism), we mean an active creator who has a significant influence and control over the process of evolution and the universe and who cares about humans as a central part of our world, who have infused humans with an immaterial soul that is their self with the common characteristics of being an intelligent designer, absolutely good and powerful and so on.
The unintelligent designs we find in nature, mass extinctions, the insignificance of humans from a biological, geological and cosmological perspective, the fact that consciousness is cognitive machinery and so on, refutes this idea. You are of course correct in that a watered down deism is fully compatible with ateleological evolution.
