My Facebook messenger wants to end-to-encrypt my messages but I don’t know what that means. I tried googling but still don’t get it, I’m not that great with technology. Someone please eli5

A really simple explanation:
I sent you a picture consisting of 3 pixels: red, blue, green, in a box.
Facebook will then take this box and encrypt it without fully looking at it. Encrypt means they just have a method of changing one thing into another. In this case, they see the pixel red, and red = banana, so they take out the red pixel and put in a banana. Then blue = dog, and green = candy. So now they will deliver a box containing a banana, a dog, and a candy.
When they arrive at your house, they will do the same thing in reverse, so banana = red, dog = blue and candy = green. They now have successfully delivered the picture without knowing what it is, and say, if they were to be robbed while delivering, the robber will find a banana, a dog and a candy instead of the actual message.
When you send a message, you have a key that just makes the message a bunch of gibberish, and the person who gets the message also has a key that can un-gibber-ise the message
