There are several problems with each of these theories, but some of the most convincing evidence comes from the fact that the disciples were willing and did lay down their lives to defend this truth and to spread the Good News to anyone who would hear. People don't go to their death for a lie. Also, there is no other rational way to explain the major shift in Judaism and the new Christian movement that happened after Christ's death and resurrection.
If what we hear is true, it has massive implications for our lives. If it is not true, Christians should be pitied more than any people because they celebrate a lie. If you don't believe he died, flat-lined, dead - and rose from the dead, his heart started beating again, breath again filled his lungs - then I challenge you to find a better answer than the Christian explanation of what happened. If you can't then the only answer is that He has "authority to lay it down and authority to take it up again" (John 10:18).
This means He is Lord over life and death, and is Lord over your life. If He is Lord we have no other option than to surrender our lives and our desires to the Lordship of Jesus. Our beliefs will be manifested in our thoughts and our actions, and we will be radically changed forever. You will not look the same as you did before. You will not act as you did before. You will be transformed from the inside out. You can tell when someone has the Spirit of Christ in them. Is it in you?
