If you have evidence, why don't you show it instead of telling me to believe in Musk?
If you believe they have evidence... that's still a belief. Some believe in God, you believe in Musk. There is no evidence, otherwise it would not be a belief.
If you believe that something can happen because someone else believes it means that you believe in that someone else (because that's the only reason for the existence of your belief).
Unless you just believe it can happen for some other reason (I don't know, you strongly wish it will happen), and you justify it by listing other people who also believe in it. But I insist: those are all beliefs.
Because Einstein believes in Santa Claus does not mean it is founded. Einstein has a right to believe stuff, too.
Correct. Beliefs are beliefs. Because a Nobel prize believes in a god does not make that god more likely to exist.
The moment we start having scientific evidence that it will happen, then it stops being a belief. But at that point you don't need to mention those names anymore: you can just show the evidence.
I don't know, you don't know, they don't know. Believe what you want, just realise that it is a belief.
