The man who interrogates this entity [which I believe to be authentic] clearly shows that he does not really have the mental capacity to follow the entity. He also asks the wrong questions based on wrong assumptions.
The entity itself shows a deep understanding of the nature of existence:
"The universe was not created. Existence is infinite. It has no end. No beginning. And therefore no creator."

English and German subtitles

"The universe was not created. Existence is infinite. It has no end. No beginning. And therefore no creator."

yea whatever ... what else would you expect a demon to say?

There are no "demons", just other species, whose existence contradict religious beliefs.

For a rather long period of my life I thought that as well but I came to realize I was misinformed and mislead as my own life experience eventually proved otherwise.

Be careful who and what you follow.

Your own experience is totally subjective and your personal belief system creates your reality. So be careful what you believe.

For decades I believed exactly as you.

There is a certain element of subjective truth in everyone's life ... but that does not negate the existence of *objective* Truth, and a plan for mankind, a *reason* for our existence, clearly and progressively revealed over millennia supported every step of the way by historical, scientific, archeological evidence of extraordinary accord impossible to account for by any other means than divine revelation.

If there wasn't neither you nor I nor anything else would even exist. What reason would I have to people my reality with someone like you, for instance, who believes so diametrically opposite of what I do?

Where did it all come from and for what purpose? ... what's 'the plan' my friend? That's the question that these sorely misguided, self centered philosophies of men simply cannot answer.

Almost all historical, scientific and archeological evidence is fake. We are living in an artificial "matrix" built by extraterrestrial beings (Annunaki) who "created" us through genetic manipulation (detectable in our genes, which clearly shows we are neither the creation of an almighty being nor the result of natural evolution) presented themselves as gods/"God" and enslaved the earth, which is not a ball drifting through "space", but a flat plane surrounded by an icewall (Antarctica) and with a dome above it. There are many other civilizations / species outside, which are called "aliens", although they do not come from "outer space". There is, however, a plan, made up by beings outside of our world (not "God"), to free humanity, which started long ago and concluded into the "Q-plan", the last part of this process, which will set us free.
As for the reason of our existence, I simply think what we call "the universe" is a temporary expression of existence itself, which is eternal.
