How can we be sure that all religions are wrong?

I gather EA is a God when SIMS the videogame was created for the first time then. I see not much of a difference and your definition in my view is lacking. I cannot infer much from such a broad definition and as such commenting or pleading for ignorance is not informative from where I stand. You can eat the cake of ignorance all you want because it has no flavour. As for "physical" Reality I don't know much about what that exactly means or entails and I know even less on the spin off on what "spiritual" is intended to mean in opposition.

In sum I am ignorant about what your ignorance is addressing!
See you around old man and take care with the fracking Covid!

Let me repeat to make myself clear, perhaps repeating may help:

I am ignorant about what your plea for ignorance is addressing!

Quite correct I used two or three more words to help you get there old man!
It is not getting any better is it? You cannot plea for ignorance without pointing at something! You are pointing everywhere so far! Have you heard of unknown unknowns?

There is a lot to unpack there, plenty of words to contend with.
For starters why don't you plea ignorance with languaging right from the get go? That would be far more honest! Who told you you know something about the validity of the word Origin or Creation? Both assume Time is fundamental when it might well be the case that it is not. To get to God and plea for something you have first to go through everything else!

Simply put, what exists happens because of nature; not because of any god or gods. The study of human evolution based on science and anthropology proves it.
The evidence on which scientific accounts of human evolution are based comes from many fields of natural science. The main source of knowledge about the evolutionary process has traditionally been the fossil record, but since the development of genetics beginning in the 1970s, DNA analysis has come to occupy a place of comparable importance.

Humans have created thousands of gods throughout human history; different gods for different race and culture. It's a human thing to create gods; it's in our DNA. The majority of humans believes in one god or another throughout history. The United States is known to be a majority christian nation. Many Asian countries believe in Buddha. Islam is also popular in this world.

It is quite sad that you think General Relativity is bullshit. You might as well throw your GPS and phone out of the window. In GR The flow of Time is an illusion as the Universe is presented in Spacetime as a block Universe where Past Present and Future co-exist!
