Anything will exist forever

This is true. At least on the spiritual level. Being born is not the start, and "death" is not the end. Both are transitions. We existed before we born on Earth, and we continue to exist after our physical human bodies die. Death does not exist. Only on the physical level. But we are not physical. And there is no time. Only the present and the eternity. So there is infinite time.

One amazing related topic is the Near-Death Experiences (NDEs). I would recommend the website of NDERF (Near-Death Experience Research Foundation).

Currently this is the largest NDE database on the internet. Currently there are 5002 NDEs on it, and it is constantly, regularly updated.

Have a nice day. All the best. Greetings and much love from Hungary.
