Our sun is also estimated reach the end of it's life in about 5 billion years. In the process it will expand and engulf the inner planets before completely running out of fuel and collapsing (but probably not into a black hole). So not quite within 7 billion years unless we have colonized other solar systems like you mentioned. I'm being pedantic though lol
