Sphere moving fast

I am a brazilian citizen. I was at universal park that night. When walking through the resort/park, I noticed there were two spotlight rays coming to the ground shining the sky. (That was a feature of the park!). When I looked to the sky, amazed vy the rays, I saw a sphere, apparently made of metal, reflecting the lights of the park/ground, crossing the sky in a medium-to-high altitude. Straight line… for 04//05 seconds until dissapear. I got shocked. Spent hours trying to understand What I have seen…. No references…. Plane, drone, shining star, nothing. I concluded that was a UFO. Came back to my country/hometown later and still do no believe what I experienced in my trip to the US, really.
