[Mass Effect] Lets say that the Turian patrol misses contact at Relay 314. How much longer would it take for humans to discover alien life, or vice versa?

Okay, lets say that Humanity leave Relay 314 before the Turian patrol catches them messing with it by, oh, how about 30 minutes. What do you think is a reasonable timeline where first contact is made between humans and other sentients?

It likely wouldn't have made that much of a difference. 

Relay 314 was an inactive relay. Even if the humans left before the Turians arrived, the Turians would've found that a previously inactive relay is now active and likely would've investigated. Probably wouldn't have taken that long for them to make contact with humans. I'd say not much would change except that the First Contact War might've been avoided.
