Space-traveling aliens do not exist in the Universe.

No,
Space-traveling aliens would not know we exist.
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 arguments:
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 arguments:
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.
