I'm pretty sure the "trails" and clouds in the OP pictures are not real. Unless there's formations of fighter-jets maneuvering up there. It could just be a day getting hazy & overcast due to humidity and heat.

Where you live dictates how the trails look. My city has them east-west and generally in the north hemisphere. It depends on the air traffic above.

Chemtrails are one of the stranger conspiracy theories. It would require a lot of "moving parts" and people scattered across the continent. Plus a lot of money. As one commenter asked "for what reason?"
Now if aliens were arriving soon and "the elite" were modifying the Earth's atmosphere to make them more comfortable? That would lend credence to Chemtrails! 😊
