haha dat funny
let me guess you think covids a myth too?
those exoplanets would take many many many years to maybe even get to, not including how long it would take to civilize or colonize, study and make sure its even safe. god gave us one earth, this is our one chance and we are screwing it up. we make a lot of pollution that messes with the atmosphere making us more vulnerable to sun flares or things that we are usually protected from. sea levels rise and the only reason that we are not able to stop global warming is because of the people that think its a myth, same thing with the coronavirus.
there IS no planet b.
