So, if Jesus said that the rapture would happen while some of the people he was talking to were still alive...

Jesus never said the rapture would happen while some of the people He was talking to were still alive...

There’s a shift happening now, Jesus isn’t returning.

It’s a shift in consciousness.

He didn't. The concept of 'the Rapture" is only held by certain sections of the Christian Church and even they can't agree on when/if it will happen. Others take a less literal view of those parts of the Bible.

To my understanding, Jesus never explicitly spoke of the Rapture. It seems to be an later interpretation of some of His messages.
