Lol wut?
These are simple contrails.
The conspiracy theories come from people who don't know their physics. DO YOUR RESEARCH, conspiracy theorists.
Here is how a contrail is formed in simple words: When water is turned into vapor, the gas rises up into the cold upper atmosphere. There it gradually cools down to its condensation point, but get this: it doesn't actually condenses. So you have a lot of water in the air, ready to turn into liquid, but still in the form of gas.
What is needed? Something not a water molecule. Any impurity. Such as a plane. When an airplane flies though the air, the different electron configurations of the metal surfaces allow the water in the air to condense, clump together, and form what we see as contrails.
And if you want to try out something very similar, (I strongly recommend that you do NOT), just microwave a cup of water. It's the same process in reverse: water ready to boil, but no impurities in it to start the changes. Which is why microwaving liquids is so dangerous: you can reach the boiling point, the water won't boil, but as soon as you touch the container, an impurity gets into the water, thus creating boiling water, and the entire thing blows up in your face, causing severe burns.
So in the air, it is just a regular physics phenomenon. Anyone who thinks otherwise needs to take a few Physics classes.
