New player confused

[Atoli]

thanks guys, How do you do this?

Speak to a player with a golden crown next to their name (a Mentor) and ask them to invite you to the Novice Network

Since this game has no world chat, people mostly talk within their FCs (guilds) and Linkshells (private chat channels).
There is an upper limit to how long you can stay in the Novice Network (until you have finished the storyline of the expansion OR played for quite a few hours) so finding a guild and/or some Linkshells that you feel comfortable in before you get thrown out into the cold, chatless world, is a good idea

(Except for a few bad apples, FFXIV's community is actually really friendly though, so if you just try to talk to random people in the streets in my experience, they will reply and it can lead to a fun convesation and even new friendships^^)
