“And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:
"And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.
“And God made two great lights; the greater light [Sun] to rule the day, and the lesser light [Moon] to rule the night: he made the stars also.

[And around millions and millions of the stars He began planets spinning; upon some He put living creatures, and upon some He did not, just to eventually bend the brains of scientists He knew would come along who thought they were smarter than Him, and would want to get rid of any knowledge of Him.]

“And God set them in the firmament of the heaven to give light upon the earth,
“And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.
“And the evening and the morning were the fourth day.”

Genesis 1:14-19

No, finding an amoeba, or finding a bull elephant on Mars, would not rule God out in the least.

And God made two great lights; the greater light [Sun] to rule the day, and the lesser light [Moon] to rule the night: he made the stars also.

To a primitive person 4 or 5 millinia ago, the sun and the moon would appear as "lights". There is no suggestion that they thought of them as different things, one a nuclear furnace and one a lump of gray rock reflecting the light from that furnace. There was one light and one mirror. They had no idea that they were spheres or that they were anything but bright spots in the nightime (Three Dog Night). That they were "lights" was easily observable with the naked eye.
