Just some of the scientific errors in Genesis 1:

There were day and night, separated by evening, before the sun existed;
There was liquid water on the earth before the sun existed;
Plants grew before the sun existed;
There is a firmament that separates the waters above from the waters below;
The sun, moon and stars are lights placed in the firmament that is just above the earth;
The sun and stars were created after the earth;

The Book of Genesis contains mythology and folklore, not facts.
