The same people who long ago had problems with Bill Cosby, Bing Crosby and David Crosby or with Van Morrison, Jim Morrison and Van Halen are today having problems figuring out which Seth is which. For nearly 100 years electronic entertainment media was Sethless but now, yes NOW...there are just too many Seth's.
Yes the entertainment world is now seething with famous Seth's. All of them white males, all of them actors, comedians and producers. So let me clear this up for you.
There is Seth McFarlane,...
Seth Woodbury MacFarlane born 1973 is an American actor, animator, writer, producer, director, and unlike the other Seth's he is also a singer. He is the creator of the TV show Family Guy and co-creator of the shows American Dad! and The Cleveland Show, and a new version of Cosmos. He is an actor, producer, director, stand up comedian. His current project is new version Orville . To confuse matters Seth MacFarlane has appeared on Seth Green's Robot Chicken as a voice actor.
There is Seth Green
Seth Benjamin Green born 1974 is an American actor, comedian, producer,
writer, and director. Green is the creator and executive producer and
most-frequent voice on Adult Swim's Robot Chicken, where he is also a writer
and director. To confuse matters Seth Green has appeared on Family Guy as a voice actor. 
There is Seth Meyers
Seth Adam Meyers also born 1973 is an American actor, voice actor, screenwriter, producer, television host and comedian. He is a former head writer for NBC's Saturday Night Live and hosted its news parody segment Weekend Update. In 2014 he became the new host of the LATER talk show.
