It’s not really only/merely speculative to understand that humanity at one point in time did not exist. You can arrive at such a conclusion via a priori, humanity did not exist when the universe was forming, the conditions were not stable enough to grow complex as we needed in order to be human and exist as such. The causal chain isn’t based on psychology it is merely observable with and in it. The cause and effect happened before man and that is how man came to be.
Something to observe existed before the observer and the observer is directly resulted from that something which is able to be observed. Science proves it by the age of the universe and it’s unlivable conditions previous to our observing it now.
It’s not the term of “god” that is not real or is illusion but merely the wrong idea behind the word that has been associated with the word wrongly. The idea of god you use and defend against is not the idea of god that was meant to be interpreted psychologically, so how can one find proof of such or if not even looking for the right thing? I am not trying to tell you you’re wrong in the idea of god you argue against, I am telling you the idea of god that you entertain as a whole is wrong and you waste your time in attempt at disproving it since that idea is not even there to begin with. Don’t listen only to the past men and how they interpreted it when you’re in the future in comparison to them and exposed to more information.
Take what is useful, discard what is poison.
Truth is consistent, always even from different perspective.
I cannot find proof of apples or properly disprove such, if the idea I place behind the word apples, are oranges.
We place the idea of an entity behind the word god by a psychological mistake of mixing ourselves with the idea of it, instead of the idea that was meant to be put behind it, which was wisdom, not an entity but a force constant in its evolution and changing.
The causal chain is as follows
unconscious > subconscious > consciousness
This is psychology of it, the chain itself however is as follows.
Physics > biology > psychology.
The physics of unconscious energy and matter lead to the subconscious single cell and animalistic biological organisms, the biological organisms then lead to a complexity of such magnitude that consciousness spawned and psychology, a balance of sorts. This psychology we use to view the past chain, biology and physics as well as our own psychology. Cause and effect evolved into conscious choice as well, it appears as not absolutely real because since psychology spawned out of biology and physics, free will spawned out of the deterministic methods that physics and biology used previous.
