What is this song named??????? PLEASE HELP :( im dying!?

Don’t you hate it when an old random song pop in your head and you only remember a little of lyrics? Please help, because i really love this song -_- But i don’t really know the song’s name nor the artist who sang this song.

I have no idea how the song goes but i think the end of the lyrics goes something like this ” .. even the last human disappear, i will be there..” The song is sang by a man, or possibly a boy group. the song categorize as R&B or slow jam. and it dated back since 2002 – 2005? For all those music lovers out there :( Please Help ME!! :( ((
Its not by the Jackson 5, I’m surely on that!

If its a boy group, theirs a strong chance it’s
I’ll be there by the Jackson 5.
Listen to it, i could be wrong because that song was from way way way back. but they coulda brought it back
