He is the firstborn of creation. As a Christian, my belief is that Christ resurrected from the dead. This is a historical fact. His bones are gone, there were witnesses to the fact, he was seen by over 500 people. Now, let's look at the law of biogenesis.
Life produces life.
Look around and show me something which is alive which was birthed from something dead. Guess what, a rock is dead. There is no life in a rock. Jesus is the firstborn of the dead. Not some missing link, not a cell from nothing, not a creature from whatever someone wants to create in their imagination because they are running from the presence of God in their lives.
