That's a natural cloud formation. They form when wind shear occurs between two air layers at different speeds, causing the cloud to bunch up or roll into ridges because of the wind flow. It happens often by where I live.

Also known as “mackerel sky.” I read a book to my 6 year old about it, if anyone here wants to learn about how clouds work.
Painting of the sky that look like this from hundreds of years ago exist.
You see this pattern all the time looking at waves in the ocean.
Idk how people get so easily misled.
I honestly believe half the stuff out out by people about chemtrails is just disinformation so that the airline companies can continue polluting our sky's while anyone that brings it up gets labelled crazy because of association to all the nonsense conspiracy myths
