A lot of them! Jennifer saw herself, Biff returned to a 2015 that by the new timeline he created in 1955, was impossible and thus Biff got erased. Marty and Doc then traveled back in time using a time machine that should no longer exist in the timeline they exist in now, however, Old Biff's desire to return to 2015, results in a possible timeline where he does, simply by punching "in "last time departed". In this possible timeline, Marty and Doc, enter the time machine with the desire that they go to there 1985. However, Doc Fails to notice that the time machine's "last date traveled" is set to 1955. The time machine's computer then calculates 1985 from the 1955 it created. This erased both Marty and Doc's 1985, but not, from the time machine's perspective, Marty and Doc. This also erases the 2015 they just left. By traveling back to 1955 from the Alternate 1985, They rewrite history agian, creating yet another alternate 1985, and another alternate 2015. The timeline was able to create a stable time loop where because Doc died soon after coming to town, history was not sufficently altered to erase Marty. Because of Doc's Earlier Paradox encountering his older self, forming a Quantum Entanglement if you will, was drawn back to Marty in a self correcting loop. Since Marty failed to die, this self correcting time loop, was erased, creating an alternate 1955, 1985, and 2015, The Alternate 1985 of Eastwood Ravine was one of self correcting Paradoxs. Since Marty was sucessful, the stable timeloop of 1955 was allowed to continue along a similar enough path that they still buried the time machine in 1885 for Marty to dig up in 1955, allowing marty to go back to 1885. But agian, 1985, is the 1985 that the time machine would calculate which is the most correct, however, the only evidence for the 2015 it's previously been to was destroyed, and thus it can't calculate it's causality, all this leaves that 2015 open, as long as Marty doesn't use his knowledge of the Future to change history. But Marty did, and didn't race Needles, and thus the 2015 of "Your Fired" is erased, but the paper isn't because the paper of 2015 was recycled from paper of 1985. A new 2015 is created because Marty and Jennifer reject the 2015 they left. Since the 2015 they left was still unstable from the tripple paradox of Jennifer seeing from herself, Old Biff using the "Last Date Departed" and Marty and Doc using the Time Machine to Return to 1985, was hit by waves of instability coming from a massivly unstable 130 year long timeline with multiple self correcting time loops. The Final Paradox, the straw that broke the Universe's back was Marty and Jennifer using their knowledge to prevent it from happening. Meanwhile at an earlier point in the same timeline, Doc over many years, buys a steam engine, uses his knowledge of nuclear physics to very carefully create plutonium in the 19th century, hops in to the time machine with his wife and kids. Since this took place before Marty and Jennifer decide to use future knowledge to prevent futute events, thus spliting the Eastwood Ravine timeline, the steam engine would go to one of two 1985s, one where Marty and Jennifer get into the accident, and one where they don't. Since this is the one where they don't, that 2015 is rejected, and thus erased, and this current 2010s is the one we'll get, not the exponentally more immpossible 2015. The only X factor is where will Doc go in his Time Train. Do we exist in the "Eastwood Ravine" timeline? Is that timeline erased by Doc's next destination? And if so are we the timeline of that 2015, or one of the many 2015s that where erased?
* The highest statistical likelihood, stemming from the majority of time travel experiences described in the English language, is that we are now in the timeline created by the [[Series/DoctorWho Doctor]] when he showed up, behind the scenes, to save both the universe and the Milky Way galaxy (or Mutter's Spiral, if one prefers) from being destroyed by the number temporal causality paradoxes that you describe. As such, if the ravine is found, there is a strong possibility that it now reads "Smith Ravine".

This is the reason Marty's siblings where erased before he was. In one timeline, Marty, confused as hell, actually gave in and, you know, with his mother. He then decides to stay in 1955. He will then try to father alternate versions of his brother and sister, But because they would have inherited different genes from George then Marty did, they where impossible, thus they where gone the night of the dance. However, Marty was still possible. Unlikely but possible. Only possible through a sperm containing the exact half of the genes he inherited from his father joining with the exact same egg that made him. When he rejected this possible future in the car with his mother he began to erase himself again, because in that timeline his mother would go home from the dance disappointed. Only by either getting his mother and himself back together, or by getting his mother and his father together, could a timeline where Marty was possible come back into being.

So Marty screws up his parents meeting but isn't immediately erased, but as time goes on slowly him and his siblings fade out of a picture until they cease to exist. It's never really explained how this works but this Troper has come to suspect its a mix of probability and uncertainty. See regardless of what Marty did there was a chance his parents would still get together regardless of his interference in history, but as time goes on that probability continually drops as things diverge from the original version of events taking the form of things slowly fading out of recorded media. Eventually there comes a point where the future either diverges from what Marty knows happened or it does not, a critical period so to speak, at which point he must either exist or cease to be based on what has happened which allowed Marty to exist up to that point.

Similarly old Biff from 2015 Hill Valley changed his own past enough that he himself would no longer exist. If he had realized this was the case and not left the grace period between making the change and the changes becoming certain he would have continued to exist, but the moment he passed the point of his changes being certain he was almost immediately erased from the timeline.
