A man named Jesus is important to everyone. Jesus is the Son of God and died for every thing we were doing wrong and will ever do wrong. You can go to Heaven by believing in your heart and speak the truth that Jesus Christ is the Son of God. By simply saying this prayer or one like it;
God which is in Heaven I know that I have made mistakes in my life. But I also know about your son which died for me. And I today accept Him as my personal savior.
Amen
(You should do this knowing that all your mistakes or sins will be forgiven.)
