I think therefore I am. We can only known that we exist in some form, we can’t know if others are even real, but its still a good idea to trest them as if they are real, because otherwise you’ll run into problems with the reality you know, whether its real or false.

In general, my guide to the truth (lowest is most trustworthy, higher is less trustworthy):

1. Internal Logics formed by your consciousness
2. Your senses, what you see and witness, what you hear, your first-hand account
   2a. If you wrote a journal, and if you can authenticate your handwriting or writing style, then you could use that to clarify any fuzzy memores
   2b. Same with photos, but be skeptical of potential modifications. We know image alteration tech already exists.
3. IRL First-hand account from people you know
   3a. People you trust
   3b. Stangers
   3c. People you are skeptical of (if they have a history of lying or exaggerating, you can rank them even lower on their trustworthiness)
4. Stories from someone that know someone that you know (e.g: “friend of your friend”)
5. Mainstream News Media, Mainstream Internet Sources, Official Reports.
6. The Internet in general.
