Yes thats what im saying.how life first happened is a mystery still,but the way we got from a single celled prokaryote to a multicellular sentient being is not.trust me or if you dont aks any biologist(im not one not yet at least)

i am asking u why monkeys existing now ? why they didn't turn into new humans ? i asked biologist a lot but the answer is "unknown" or smthing

Thats a rookie and easy question,see the monkeys dont turn into humans they never ever did.this is misconception commonly asked by people.we shared a common ANCESTOR with monkeys they dont turn into us or we turn into them.thats just not how evolution works.the monkeys exsist because they fit their envoirment best.and tell that biologist to rewise on his decision to study biology because its obviously not working too well for him.(kidding)

wait wait . explain how we have ancestors with monkeys in common while our roots is not same ? this is a paradox !
and another paradox if u answered the first ! how the ancestor seprated once in monkey an next in human ?

What did i say our roots are not same?are roots are the same.infact we have same roots with every single living being on earth from bacteria to whales, its just the matter how much you want to go back to find that link.think of it as a tree, tree of life if you will.each species now is a branch that goes back to the main body of tree(they all connect at the bottom)
There is many ways for a new species to rise one of them is that a part of population gets seperated from other part,now we have 2 group of organisms still same species but in time as their envoirment is diffrent, diffrent traits get selected so as time passes they diversify from each other more, hence they might become diffrent species.

ok here is what i want ! the creatures as u say is just like a tree , a tree with different species that got their diffrences and their complexity due to their conditions to raise the chance of survival! now why some of them are highly complex while they are not a survival species ?
i mean , for example housefly just survive for 4 weak average ! why ? all of this complaxity for 4 weak ?
and another thing ! u say creatures rooting from bacteria ! so explain , how first roots of us seprated without a pair ? we have men and women with differences , obviously their se*xual organs are not same ! why in a male one type of organ will chose to make survival and in female another ??
why existance of male is incumbent for female survival and vice versa ?

Alright
The complexity is not a direct matter to how succsesful a species is,for example in some point of starfish evolution they had to go back and become simpler so they simply would be more fitting to their habitat,remember number one piority for all animals is to survive and pass on their genes literally every single organism wants to do that.house fly is complex because it benefits him.back then there was only bacteria but some grow bigger and engulfed smaller ones(these were ancestors of first eukarya)they did this because it benefited them and they could reproduce more and be efficent so by natural selection this kind of bacteria were chosen over others so they grew in number and branched off.as for s.e.xual reproduction bacteria dont have s.e.x.ual reproduction,1.2 billion years ago first protists started to s.e.x.ually reproduce, the advantages were tremendus.why?because their offspring variation greatly increased so they increased the chance of making a perfect fit by more variation.and for humans our bodys dont choose we have some organ over the other,this is determined by our s.e.x chromosomes that affect embryo development in fetus.(basically they change hormon balanced and that affects the s.e.x of the kid that is born)

wait ! how the first protists started to ***ually reproduce while none of them had any se'xual organ ?
this cant be coincidence because this wont raise chance of survival without another pair !
natural selection can do nothing until favorable variation chance to occur !

There is a whole big article about this google origins of ***reproduction if you are really interested in learning.my hands are tired [emoji4] if u didint find it i can give you the links.

actually my last sentence derived of "origins of species" from darwin ! but i try to find translated version of that book and read it . tnx

Your last setence is correct (not only because its from origin of species)actually i think a wikipedia article would do fine.i hope you read it

OK also u can download this video :

this is about some experiments done to prove darwin theory but they got lost !
