A hypothetical Isekai scenario

You, an overworked worker with no social life are going home one day, when unfortunately, you have an unpleasant encounter with Truck-kun. You see God and He tells you, that you're His child and that He'll send you back to earth to save everyone. You wake up as a baby and it's not long before you realize: Your JC himself. What are you doing from now on??????? How will you affect history??? How do you avoid your fate??? How many seasons! How much controversy?!!??!!!! Discuss.
