I am not saying Christianity was founded by that person or alien, but by the people trying to explain the events that were happening. The complexity of the religion could easily be the result of human imagination shaping it for a thousand years. Just like the cargo cults of World War II created strange rituals in hopes of bringing back the metal flying machines filled with food.
Keep in mind that the stories of the Bible weren't written down until about 1000 years after Jesus' crucifixion. That means the stories of the Bible were passed down from generation to generation for 1000 years by word of mouth. Now we know that when you pass a passage by speech from one person to another person, the passage usually changes as human memory is not perfect. The same changes could have happened to the Bible as people left out some parts and added parts to it over those 1000 years.
And it is hard to know what Jesus looked like because no one drew a portrait of him during his time, and the first person to do so did 600 years after his crucifixion and he based it on how people described him, who received his description after it has been passed down for 600 years. The artist most likely used his imagination to draw most of him.
Aliens may have started exploring this planet thousands of years ago. Have you ever heard of the Nazca lines in Peru?
Entire mountaintops were cut off and all sorts of lines that resembled runways resembling an airport were formed. Plus, the mass of the mountaintops was nowhere to be found. And the animals that were drawn on the ground can only be seen if you are flying from above. Could ancient tribes have been trying to communicate with someone in the sky?
Them crop sircles are simply this:
Idiots with grass cutters.
