Did Earth capture the Moon?

Darren M. Williams, et. al. has revived the capture hypothesis in his recent paper

H/t Tony Dunn (X)

If a binary planet system passed close enough to Earth, it could break up the binary pair capturing one.

Sprites, or red sprites, are captivating atmospheric phenomena occurring high above thunderstorm clouds in the mesosphere, typically between 50 to 90 kilometers above the Earth’s surface. These electric discharges are triggered by positive lightning strikes between a thundercloud and the ground.
