Given the hypothesis this happened, is it reasonable to say that They are not coming. Everyone is here and no one is hiding. We just can’t look!!

The experience I report as hypothesis is:

I saw very closely a slow, very very slow moving spacecraft, building size, through my kitchen window, no sound, color graphite, shaped like a whale with a tail pointed downwards, floating at a height around the 4th to the 10th floor range (because of it’s size), no apparent windows, it did a turn around as if it was watching me watching it for about 3 minutes, then slowly moved away as I was losing sight in the horizon. I didn’t register the day, time or took any picture cause I wanted it to repeat somehow and thought that trying to capture the moment by registering it I wouldn’t be able to see nothing alike again since back then there was a lot of people at the streets and in other buildings but for some reason it was like they couldn’t look, like they were tuned not to. Anyone?
