Please show/tell me the verses you are referring to...
I want to make sure I am responding with proper context because these sorts of chats about the earth seem to be rife with misinterpretations. So please tell me which verse you're referring to that says the earth is stationary. I looked for such a verse but couldn't find any.
I think
maybe you're referencing Psalm 104:5 or Psalm 93:1 but I am not sure. In any case, those aren't references to physical movements. If we are going to have a conversation about this then we need to make sure we are speaking the same language.
If you'll study how the Hebrew word for "moved" in Psalm 104:5 and Psalm 93:1 are used in speech in numerous parts of the Old Testament, you'll see it isn't about something physically moving or being physically stationary.
The way "moved" is used is about something being steady and reliable. Another way of putting it, which is the more literal definition, is that the Earth will not waver. It means the earth will not waver, it has good performance, it can be trusted. This is more along the lines of how this should be understood.
For your convenience, here are some to help you understand how the word moved in Psalm 104:5 and Psalm 93:1 are used in speech:
Psalm 10:6, Psalm 13:4, Psalm 15:5
I hope that clears it up a bit better.
