Easy 10 points: Do you believe in aliens? Why or why not

Well when you look at it , our sun is tiny canister to others . Like a house to spec of dirt and vice versa . The sun is one star of trillionsbin a bowl called the milky way , our galaxy .. Billions of our stars have planets anywhere from 1 to 20. Of that there are even more dwarf planets .
When I say billions , I don't mean 1 I mean anywrr from 200 to 999 billion planets .
Now try to graspnon that .
There are trillions of galaxys tons bigger and smaller than he milky way our galaxy
100 000 000 000 000 000 000 000 (100 Sextillion) Stars in the Universe. and i assume you mean can't but it would take more than 4 years (travelling at 186,000 mps) to reach the nearest star with no planets, and 20 years to reach one that does

Given that info , to think were alone is complete ignorance

Yes, I believe there is. Out of all the stars in our galaxy alone, there are several thousand that we already know have multiple planet solar systems. The atoms and molecules that make up plant and animal life here came from old stars that died millions of years before our sun formed and these elements are found all throughout the galaxy. Life is chemistry and chemistry happens everywhere.

Yes I have studied this extensively and from the data ive collected it's pretty interesting. First off planets in the habitable zone can vary in size possibly. The size of the planet is directly related to it's gravity earth is 1g this is the core element to all life on earth and of course the way humans are shaped a swell skeletal frame etc.. Planets that are to small cannot harbor an atmosphere where larger planets can but will have maybe 1.5 to 2 gs making short stubby creature the norm. Grey aliens would Develop on a planet such as earth with maybe 0.6 gs that's whys tall skinny frame maybe. There are many variables such our star type galactic habitable zone but it would take an essay to write it all.
