Lights looked like stars but moved fast and hovered, changing direction. They aligned with each other, formed lines and shapes.

I saw two different types of objects. The smaller, farther ones looked like stars but they changed direction and moved at impossible speeds. They could not have been meteors because they didn't burn out, they just hovered and moved again in a different direction. They aligned themselves and shifted all at once, maintaining the shape. There seemed to be some lights "leading" and the others would shift around it. They made shapes that looked like a rhombus and like a backwards number 4- all forming completely straight lines. At first I just noticed one light moving, but then I noticed all of the others around it were moving too. There were too many to count and they kept shifting. They all started moving north, to the point where we had to turn our bodies to see where they were going. When we looked south, the sky where we first saw them was black. They all seemed to be clustered/ heading towards an area offshore, around north Rehoboth or Lewes. They were mostly coming from above the sea but some seemed to be coming from land or across the bay.
The other objects were lower and looked more like drones, but they moved very fast so it was hard to tell. I observed 4 lights on the bottom of these crafts, 2 white above and 2 red below. They flashed in quick succession counterclockwise- white, white, red. The fourth red (bottom right corner of the "drone") occasionally flashed but not consistently. These crafts were also moving erratically like the smaller objects and seemed to be heading in the same direction.
We watched for about half an hour, walked back to the car and drove home, and when we got home about 20 minutes later we could still see them above the house moving towards the ocean.
