Neowise Comet & me ! We are NOT alone in the Massive Universe !

Comet Neowise will NOT visit us in another 6800 years ...! Will earth & humans survive till them ?! Humankind has supposedly conquered earth which is not a fact by rapid development of science in last 200 years.. The vastness of universes and its continuing expansion in sync with human knowledge expansion ...This visiting celestial solar system incumbent is a proof how little we humans know of universe...! there may be another comet or asteroid hurling in space towards Earth .. ready to destroy Human kind & all Life ...! and then another primitive life will restart again ... Dust to Dust ..Me & you are just a Cosmic particle !
