Isaiah 45:7 tells us that God creates calamity and Genesis tells us that He created Light and darkness.
It is up to you to choose what you follow however, just as it was Satan's choice to want to be higher than God and he was tossed out of Heaven. Just because there is evil doesn't mean you have to follow it. The choices you make is what God will judge in the Last Days.
There wasn't a void with nothing in it but the void and evil in Genesis. There was nothing and then there was something including darkness and evil when God said let there be light. Then God separated the light from darkness ever since.
I always get exercised when people say "God wouldn't do that!", when I can show dozens of verses that show God giving plagues, killing evil people, splitting the earth open, and killing Arron's sons. God killed Judah's 2 pagan sons just because they tried to marry Tamar. God killed every man woman and child on earth in the Flood and will kill 2/3 of the Earth in the Last Days. One angel killed 185,000 men in one night and killed 2 followers of Jesus for lying about selling their property. God has no problem killing to get what He wants. Remember why Saul was not allowed to be king any longer.
This is not possible as God is good. The privation of good is evil. God has nothing to do with evil.
Gen 2:3 And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.This verse distinguishes between thing that are created and things that are made. Three times in Genesis 1, the word created was used. He created physical things (body) then living things (soul) and finally man (spirit). It does not say that he created light in Genesis 1 or in Isaiah 45:7. God is light but darkness and evil did not exist
