Space-traveling aliens do not exist in the Universe.
See 4 reasons to agree: [Most forthcoming.]
• The likelihood of another planet existing which is capable of supporting/evolving life is low.
• Contra abiogenesis, life cannot come to exist on its own.1
• Existing microbes cannot naturally evolve complexity.
• Existing complex life cannot naturally evolve intelligence.
• ~6.25^18 stars with planets exist.2 (That is a lot of opportunity!)
Space-traveling aliens would not know we exist.
• …Our radio signals have only reached .0011% of our own Galaxy.1
This is relevant because if aliens exist (see challenges above), it is unlikely that they are within this nearly microscopic pixel-sized range within the Milky Way that our signals have reached.
Aliens would have no desire to raise Jesus.
See 2 reasons to agree:
• The cost: 23,000 years just to travel .001% of the Milky Way.1
• Resurrection aside, Jesus had no prospect of influence. Other candidates for their resurrection project would be overwhelmingly more attractive. • Jesus would reject alien values that would inevitably compete with Judaism. (Jesus remained a Jew.)
This is relevant because any proposed alien resurrection of Jesus would require a heavy investment on their part (see above). Aliens are mysterious, but no proposed evolutionary survival advantage would lead to aliens having values that result in their desiring to travel to Earth, raise Jesus, and let him teleport to just a few followers at a couple sporadic times.
Aliens would not have the technology to resurrect humans.
See 3 reasons to agree:
• Such technology is in principle infeasible.
• They’d have no experience with cellular life on earth.
• They’d have no experience with human anatomy.
• They'd be incapable of re-producing Jesus's psychology and memories (for both rapid corpse brain-decay and mind-body problem reasons.)
This is relevant because without the requisite technology, aliens could not raise Jesus even if they wanted to.
Jesus did not mention or attribute his resurrection to anything mysterious or alien-like, but to the God he proclaimed during his earthly ministry. This is relevant because if aliens raised Jesus, then it is unlikely that Jesus would be so confident that God raised Him from the dead. After all, Jesus was ostensibly able to ascend, appear, and disappear when and where he wanted. He was also apparently able to empower his disciples with the Spirit and ability to perform miracles.
In addition to raising Jesus, such powerful aliens with their given purpose would likely be able to perform far more wonders to enact that purpose. This is relevant because aside from Jesus's resurrection and relatively hidden miracles in the early Christian sect, nothing particularly flashy quickly drew the world together or influenced it in a discernably valuable way to extraterrestrials.
