The best answers are in the Bible.
GOD, the GOD the created you and me breathed the Breathe of Life into us so that we may live.
He is the one true God, and he loves us so much that he sent his only son to die for us on the cross, so that we may live. And by dieing on that cross, He took away all of our sins.
Easter, or Ressurection Sunday, is the the day the Jesus, HIS Son and our Savior, rose from the dead.
He also Rose back to heaven, and in return, sent us the Holy Spirit to guid us in our lives.
But there willl be a day when he will come back for everyone that beleived in him and followed his laws
