Samsung galaxy tab GT-P1000 system update

hello everyone
so i have a samsung galaxy tab gt-p1000 and i have had it for about 6 years now and the problem is that it still has the same system as the one it had when it was new and wouldn't update . it has android 2.2 !!! And of course that doesn't work anymore ..so no app store no nothing ...i really love this tablet and would love to be able to use it again . so what can i do ? how can i update it ??
