How did ancient aliens come here?

• There has been many questions if ancient aliens existed, how did they get here? How did they move around? 

           So did ancient people see ancient aliens flying planes? "what they called gods".

           An evidence of flying object that goes back to approximately 200BC is the Saqqara Bird.

• More then 7000miles away from Saqqara(Egypt) in El Dorado(Colombia) a Tolima gold model of a fighter jet was discovered in which goes back to 500AD.

       Could this be a coincidence that more than 7000miles away from each other, two different civilization was thinking about same idea of making a flying machine or the did they see extraterrestrial flying objects.

           Question arises that where would ancient aliens land their flying machines. One of the evidence of landing could have been Palpa on the Pampas de Jumana about 400km south of Lima which goes back to 400 and 650AD which would be a preferable runaway for the ancient aliens of El Dorado(Colombia).
