The Six Days of Creation Lasted 24hrs Each

Each of the six days of creation probably lasted for 24hrs each - not for a thousand years. The Biblical day starts at night, followed by day. And each of the six days of creation consisted of one period of darkness followed by one period of light. If the darkness lasted 500 years, followed by 500 years of light, photosynthesizing plants could not have survived. It also would have necessitated that God later sped-up the speed of the earth's rotation on its axis - but the Bible doesn't mention that any such speeding-up of the earth's rotation ever occurred.
