A point of infinite energy is not “nothing”
The entire universe was created from something, but not something tangible to the human mind.
Absolutely right. In fact, it is pretty much impossible to define what "nothing" is. As soon as you define it, it becomes '"something". Philosophers and scientists have grappled with this for centuries. I like the definition put forth by Johathan Edwards (the pastor, theologian and philosopher - not the politician.) "Nothing is what rocks dream of".
