Thanks for the reply, jpm.
About the Sabbath, just now I checked in the internet and found out as followed:
Adventists believe the days of Creation are literal 24-hour days—just as we measure a day today.
https://www.askanadventistfriend.com/adventist-beliefs/creation/
and another quote from the same website:
when the Sabbath shows up in Genesis 2:2, it picks up the same order of counting a day. It started in the evening, progressed through the morning, and continued until the next day began at sunset the following evening.
God provided a full 24 hours for His children to spend time with Him and enjoy what He had made for them.
Now it is known that according to Young Earth Creationism (YEC):
the first moment of the first day of creation began in the evening.
This is what is actually bothering me (as I position myself as a YEC). I reach an awkward situation:
“If the first day of creation began in the evening, then when did the first moment of the first day of creation begin from the viewpoint of the other part of the Earth?”
I really hope that there is a YEC/SDA/Literalist member here who can explain it to me.
