There are billions of billions of billions of stars out there.
1,000,000,000,000,000,000,000,000,000 as a rough guess).
Even if .0001% has planets, that means 1,000,000,000,000,000,000,000 would have planets.
Even
if .0001% have planets that could sustain lift,
100,000,000,000,000,000 would fit (one hundred billion)
Even if .0001% had life develop,
1,000,000,000,000
And if .0001% devolved into "intelligent" life
That would be we could have 1,000,000,000
That's a billion planets that could have intelligent life.
