That Professor Kasting measures lifespan using time as a frame of reference makes me wonder ... if you say creation started at a definite known date, say 4.6 Ga ago it would not be entirely true, in as much as, that timespan will have a meaning only with reference to its immediate past moment, 4.6 GA plus a few seconds/hours/days/.../years in the past. So how would you account for that timespan? Just because you (humans) cannot measure or know or relate to it does not mean it didnt exist in the past. > I do not subscribe to the purpose of intelligence as universe's > creation boundary condition.

Intelligence is again a relative concept ... maybe abstract too, since humans consider themselves to be a higher evolved form than an animal/bird other species. Someone should ask them what they think of us !? -- .
