Answer:
So the evening and the morning were the first day (Genesis 1:5).
Yes, Lee, the first two verses of Genesis 1 describe events on the very same day. I presume you ask the question because you have heard that supposedly millions of years passed between verses 1 and 2. You can find the answer to this question if you read closely what Genesis, God’s Holy Word, says.
When God first began to create, He created the heavens and the earth. That’s verse 1. They weren’t completed yet. Verse 2 describes what they looked like so far. The earth was “without form and void” (without life and incomplete). Each day God completed a bit more until, after six days, it was all finished. He called His finished work “very good.”
And Lee, you need to know there are many qualified creation scientists who do not believe in millions of years and who have done much scientific research that confirms the universe is only thousands of years old. When you read the Bible carefully, there is no doubt that verses 1 and 2 describe part of the first day.
