Hi Gina, Yes this is the big debate about creation. Was it a literal 6 days or was it over 6000 years. If it was over 6000 years than yes the plants could not make it. I believe the text show 6 literal days. so the plants could receive light the NEXT day. Exodus tell us Exodus 20:8-11 8 “Remember the Sabbath day by keeping it holy. 9 Six days you shall labor and do all your work, 10 but the seventh day is a sabbath to the Lord your God. On it you shall not do any work, neither you, nor your son or daughter, nor your male or female servant, nor your animals, nor any foreigner residing in your towns. 11 For in six days the Lord made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy. If you think 1 day is like 1000 years than the Sabbath could be a 1000 year rest! The Hebrews would NEVER understand the 6 days of creation to be anything other than sun down to sun down. The day or YOM, word for day in Genesis 1 is a literal, 24-hour day
