My first SCP. It's basically an event that happened once and hasn't happened again. In the event time was frozen but somehow security cameras were able to capture the event anyway and record exactly 24 hours of it. During the event, strange humanoid creatures of unknown origin appeared at multiple locations around the globe and started doing research on every living thing they came across for 24 hours then they left again and time resumed.
I think it sounds weird but that is likely just in my own head.
