118- Meaningless Word

The Mechanism Of The Creation
According to this picture, scientists have mistakenly imagined that the universe is finite. They believe that the universe was created 13.7 billion years ago after a massive explosion (Big Bang) and has been in constant expansion ever since. Please do tell us what was before 13.7 billion years?

Some say that time exists “from the beginning of the world until the end of it.” Such meaning and interpretation of time are incorrect. If we ponder this argument, we find out that this is more of an unfounded basis than one obtained through contemplation and research.
Do you realize how nonsensical this statement is?
What do “the beginning” and “the end” of the world mean? What beginning and what end?
If you claim that the world has a beginning and an end, tell me, where are its beginning and end?
