Circular light resembling a star moving very erratically in the sky.

On 9/2 at 10:00pm, my best friend and I arrived at the lake for our usual weekend night fishing routine. He has been a contractor all his life and very close minded. He deals in facts. I am open minded, Spiritual/Wiccan. I worked in healthcare all my life. Subcontracting with him when I went through nursing burnout. We have been friends for 35+ yrs.
At 5:10am 9/3/22 he happened to be looking at the sky straight out in front of us. I was baiting my hook when he said “Yo! I need you to look at this and tell me if I’m crazy.” When I looked up I immediately saw what he was referencing. A flashing “ball”/“sphere” of light. At times no bigger than a star. I immediately grabbed my phone (IPHONE 12 ProMax) and started recording. It flashed continuously and moved erratically but smoothly up/down L/R like the way we move our hand to write. Staying in the same small area. The times it got smaller/faint it was almost as if it traveled away (backwards). The same applies to when it would appear a little larger. As if moving closer (forward). It never made a sound. We watched it until it literally faded away (farther away) a few minutes before dawn. I immediately called my husband who is from that area to tell him and he was not shocked. He asked if we were in a specific location of the lake. (We were) Because “stuff like that has been seen out there for as long as I can remember.” Try zooming the video in a little to be able to see it when it gets smaller. It does get hard to see at times through the lens.
