What are the trails that planes leave on the sky?

[Vipassana]

Does anybody know what these are? I ask the people around me and they don't know what it is. I've been told its a contrail but i don't know if its true because i've also been told its a chemtrails. I am not propagating a conspiracy thread, I am just genuinely curious as to what these are & why they exist. I don't think commercial planes leave this trail behind & the jets that are high up in the air leave a trail but it dissipates within a few seconds. These on the other hand are much more closer to the ground & remain in the atmosphere for hours on end creating a very thin layer of cloud. Interestingly, these planes tend to fly right under the sun (from my point of view), diluting the suns intensity. I've heard stuff about geoengineering and the attempts to cover the sunlight to reverse global warming however I think that's like putting on a band aid to cure cancer. Also, during the lockdown, there aren't much flights taking off however these planes come by every few hours. I'm curious. 

some of the questions I have that I hope you guys can enlighten me on.

1. Why do they exist? What is the purpose?

2. Whats the actual substance? is it condensation or is it chemicals like some people convey? 

3. Is it prevalent all around the globe? Do you guys see it where you live?

@Consept interesting, don't know if its the best source but I've acknowledged what it said.

@Consept I just came across this government article. Check out page 6. I doubt its merely a contrail.

Stratospheric Sulfate Injections—A spray of sulfates into the second layer of earth’s atmosphere 13 could reflect incoming solar radiation to reduce absorption. This process occurs naturally after a volcanic eruption, in which large quantities of sulfur dioxide are released into the stratosphere.14

Solar radiation management methods, which you could also call sunlight reflection methods, seek to reduce the amount of climate change by reflecting some of the sun’s warming rays back to space. We know this basically works because volcanoes have cooled the earth in this way. Preliminary research suggests that we could rapidly and relatively cheaply put tiny particles high in the stratosphere and that this would cause the earth to cool quickly. Nobody thinks these approaches will perfectly offset the effects of carbon dioxide. For example, these methods do not address the problem of ocean acidification. However, preliminary climate model simulations indicate that these approaches could offset most climate change in most places most of the time. While these approaches may be able to reduce overall risk, they could and likely will introduce new environmental and political risks. - STATEMENT OF DR.

The article is about proposals for possible climate-interventions from 2010. No one says that they have been implemented already.

Now you could argue that they had been implemented in secret. But why? In the U.S. it would lead to less corn growth. And last I checked the president wasn't too keen on climate-interventions.

I believe its already have been implemented based on my observation alone. These trails are way too consistent to be contrails. They almost seem scheduled where I live.
