Thank you for a great response

Here’s a ridiculous question....and I bet it will get loads of abuse....This is hard for me to put into writing, If different colours of light are different frequency’s of light that we can see, and higher frequencies are ultra violet and microwaves that we can’t see. Maybe aliens look at earth, and all they see are ultra violet light and radio waves as their eyes have a different frequency response. They look at our plannet and think it’s all blurry and weird..... kind of what Jupiter looks like to us.... maybe when we look at Jupiter we’re actually seeing their WiFi network or something.
