Being cannot come from Non-being

[Mister Agenda]

According to the available evidence, our universe was once in a very hot dense state, then suddenly expanded to begin forming the cosmos we can observe today. In other words, our universe is a transformation of a previous 'state of the universe'. We don't know 'where' that previous state came from. It may have existed eternally as a the hot dense sum of all matter and energy or it may have periodically or randomly fluctuated between that state and universes as we understand them. There are multiple ways our universe could be eternal, not requiring a beginning because it has always been. Given that the beginning of time is tied to the initial expansion, it is fair to say the universe always existed on that basis alone.

If our universe did 'come from non-being', the physics and math don't have a problem with that either. It is a category mistake to apply a state of affairs within the universe (causality, energy, entropy, matter, space, and time) to the universe. Events within the universe requiring a cause does not translate into the universe itself requiring a cause, any more than a wall made of indestructible bricks requires that the wall itself be indestructible.
