8th: To become a biblical earther, get saved by believing the Lord Jesus Christ (God the Son manifest in the flesh who created the earth & firmament) died & rose for salvation from your sin

The Gospel is the Lord Jesus Christ died, was buried & rose from the dead
Christ died for our sins according to the scriptures; and that he was buried, and that he rose again the third day according to the scriptures:
1 Corinthians 15:3-4 KJB

Romans 10:9 KJB
that if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. 
For whosoever shall call upon the name of the Lord shall be saved.

To be saved, just genuinely pray, "God, I believe the Lord Jesus died and rose. In Jesus' Amen."

If you get saved, you will have everlasting life & get to rule and reign with Jesus forever. If you choose to get saved, you'll be redeemed from your sins & be eternally secured in God the Father & God the Son's hands (John 10:28-29 KJB).
