I have no idea what consciousness is.
That’s the point.
But mine exists. I’m not sure about yours.
Science has no idea what consciousness is either. Quantum physics touches it, but doesn’t even attempt to examine it.
Are you arrogant enough to believe that your consciousness is the highest degree of consciousness in the universe?

So you’re not just challenging atheists on the nature of consciousness, you’re challenging every belief system known to man about the nature of consciousness.
I think you might be a solipsist.
And, it would be against the rules for a philosophy major (10s of thousands of years ago) such as myself to not state the following: the philosopher of science can tell you exactly what consciousness is; it is the electrochemical activity in your brain.
So tell me what these belief systems say about consciousness that is concrete.
And "electrochemical activity in your brain" explains no more about consciousness than pretty colors on an MRI screen.
Consciousness is the fundamental aspect of existence.
