While my wife was outside smoking, she observet a shperical gold object emitting extremely bright white light. she called me over and i saw a very bright white light. the object was moving very fast, and was moving in a zig zag type pattern but like it was just appearing at each zig and zag.It also seemed to be dropping and fluttering. it quickly disappeared over the tree tops. we are very familiar with all types of aircraft and this was not a conventional human aircraft and not an atomospheric event. this is the first time we have ever seen something in the sky and knew it was a ufo.
