See my former post about the word "eternity".
Timelessness is ONE of the ways to use the word, only one.
But that is not important, eternity is equally as invalid as infinity, I am talking about
real systems.
Beginning is required or one will end up in stupid illogical circles.
I direct you and Taosaur to this chapter in the book trilogy "My Big TOE".

See also page 279 about infinity and how it relates to reality. Though some concepts/terms are unknown to you when the book is not read in order.

Happy reading, you won't regret it! :)
If you find the reading slightly interesting I advise you strongly to read the trilogy for free or buy the books.
