So, there you have it, the MCU is officially Earth-616. You can pick holes in the decision, but it's what Marvel Studios has gone for and will likely stick until this franchise is rebooted post-Avengers: Secret Wars.
Peter Parker, the Amazing Spider-Man, is the mainstream and original Earth-616 incarnation of the character and appears in almost every piece of Spider-Man related media. All other "spider-men" are derived from him.
