Don't joke. I was at my wilderness cottage in northern Ontario about six years ago.
Bright blue sky, beautiful sun, warm air, no bugs ... I was alone ... the world was my own. Then a round white object the size of the full moon slowly drifted overhead. I thought maybe it was just some thing that was blowing by ... a piece of garbage, plastic or even a party balloon. So I ignored it.
It stayed in place for an hour and I thought it was weird.
After hovering in place as clouds slowly started to move overhead ... I became worried. It's freaky to see an object stay in the same spot in the sky for eight hours and it isn't the moon or the sun.
It stayed until sundown, then finally moved away.
I researched it and asked around about it days after.
Turns out it was a new experimental balloon system they launched from Timmins, Ontario. Some new system someone was developing to raise rockets into high altitude and launch them from there.
But for a few days I was really freaked out.
