if there's life on earth, why can't other planet have life?
i think the very conventional idea of alien is silly
and i concur with wolfram's view on alien
the current pop idea is that, there might be alien, and they r just like us, or, they r diff from us but still really just like us.
basically, human animals project what it might be out there using human animal's brain.
violates a fairness principle.
which shares the some root as, who r we, why r we here?
or, in other words, did god created alien too?
before we can guess if there r aliens or what they might be like, we sorta have to answer the question where do we came from
u can't surmise aliens sans surmising our own origin.
and, if u take that our own origin is just molecules spontaneously form cell life... which scientifically we r not certain, then, we also r uncertain scientifically how this possibly can happen elsewhere.
the whole pop notion of alien and all the debates, can be said as a human fantasy
until, one day, we actually have some evidence of alien.
right now, we just dunno. as much as we dunno where we r from
let me try to monolog an essay, on this issue, explore the questions.
typically, the question is this: if there's life on earth, why can't other planet have life?
i think the answer is, yeah maybe, but we dunno.
for example, there's car in usa, why can't other continents have car?
as an analogy.
sure, other continent may have, or may not.
as far as we know, indeed, many doesn't, until we put cars there.
or, basically, depends on, whether they invented car there.
or, put in another way. we have shoes, why can't other places have?
or, we have blue eyes, other places must also have?
so u see, via this analogy, we can see some ways to dissect the question: there r life on earth, why can't other planets have?
involve quite a few things, that we dunno the answer.
and basically, it comes down to, why there is life on earth?
who made it?
what made it possible?
or, as far as we understand, how is it possible, for molecules, form life?
like, put in some colored potion in a jar, shake it, and suddenly, u created life.
put it in a warm place, after a week, warms will crawl out of it.
is that true?
is that true, in nature, some river, rain, earth, meet together somewhere somehow, and after a lightening strike, suddenly, it became alive, and it start to replicate, and eventually became a monkey?
do we know?
how much we know about this?
isn't this, necessary to know, in order to guess, whether there r aliens?
to answer that question, here's what we know so far, according to wp
Image
so the conclusion from this line of thinking is that, yeah there could be life elsewhere, but we have no clue. since we dunno how we r made ourselfs.
Fermi paradox: probabilistic argument: there's life on earth, there r billions other planets, therefore, there must likely be life elsewhere?
now, what about the probabilistic argument that, since there's life on earth, but there r billions other planets, therefore, there must likely be life elsewhere?
right. a good question. but that doesn't seems to indicate any good probability.
because, in the universe, a billion is a very small number.
maybe u need a mega billion planets to have a chance.
or maybe u need giga mega biga billion planets.
or, maybe u need a number, that we cannot even fathom, for the probability to approach 0.1%
because, we dunno, what is the probability, that life occured on earth.
if we know, that the fact life on earth, is due to a probability of 0.1 , then, that make things so simple. we just need 10 planets, to be sure, there's a life among them.
so, i think answered the question, of that famous idiotic question by a lose mouth myth.
i think there's philosophical argument too on the issue of alien existence.
namely, we dunno what is consciousness.
or, soul.
some say, we r just a dream in a matrix.
some say, reality exists, as atoms. we r just result of atoms as emergent phenomenon.
some say, for sure I exist, because i think. but u may not exist. u r just my imagination.
and the mind body problem. how is it physically possible, that ur will, make u walk?
can i see ur will?
so, these thinking questions, aka philosophy, puts the existence of alien in a diff light.
if u go by u think therefore u r, thus i no exist, and alien no exist neither and never will. only u exist.
if u go by materialist, then nobody exist, nor alien. it's all just atoms jamming
by the above essay, i think, the pop argument and debate, about aliens, is just human animal fantasy.
