Apart from the facts that Oasis wouldn't even have EXISTED without Liam, as he formed them, gave the name and been the frontman and singer, and Noel wasn't a singer, another proof is that nowadays the "High Flying Birds" aka Noel "solo" make songs that one can think they are good, and think that he's a good songwriter, and he improved his ability with experience, etc., but there are no "legendary" tunes, songs that people will hum for years.
It was LIAM making them epic. He was more important than the songs. And then the fans followed everything about the Gallaghers. At those times, it worked like the "boy bands" the new generation should follow, as they belong to their shite times. The girls were attracted by Liam, obviously not Noel, as he was ugly as fuck, and that was fundamental.
Oasis was LIAM's band, that's why Noel hated them, in everything.
Noel might play an Oasis song but going to one his concerts, you will never feel like you're @ an Oasis gig.
Besides, if they read at least one books written by the people who were there, Noel confessed his masterplan was to become famous through the media, not the music. All the (fake) arguments with Liam. He USED Liam.
