Do you remember what facebook was like in black and white?

Plato Notes would've been in black and white. In fact, it would've been coming out of a teleprinter. So what you say is not as silly as you think. Also, a ZX81 could almost certainly be used to access FB Mobile if interfaced with a mobile itself. Taking that back, you could probably use a PDP-11 and a teleprinter to access it if you were sufficiently geeky about it.

Moreover, since this galaxy has been around for over 10 billion years and this planet is only 4.6 billion years old, the chances are that even before this planet came into existence, something already existed somewhere which made Facebook look like a cave painting.
