There are obviously many flaws with it, probably the most well known one - how life started. Darwin in his Origin of Species, never actually answered where life started or came from, or how it did. Evolutionists can never answer those questions. Mostly evolutionists will say their theory doesn't adress the question of origins, but clearly this is false. They teach Humans came from apes, fish or whatever but can only reduce us to a tiny cell. Where did this cell come from? They never can answer.
Also evolutionists can't explain the existence of the conscience which is not matter.
Alright, lets compare two phrases and play spot the difference.
1- The origin of species
2- The origin of life
These are seperate for a reason. The same explaination that works for one. does not work for the other as its not the same subject.
The origin of species deals with what toke place that we have so many different species. Namely evolution, which is well evidenced and we understand how this works.
The origin of life deals with how life came to be on earth. There is no shortage of hypothesis of how it might have happend some better then others. The trick is though we dont have enough evidence to settle this matter so we honestly say "we dont know yet", which doesnt mean we dont have any idea but only that we cannot say which idea is correct.
If you are interested in knowing some of these hypothesis thats possible.
Just for fun ill give you a random answer, life started on earth when a unknown entity seeded life here. There you go now you wont have to go around saying you never got one
In recap, its not that we dont have answers that are possible. Its that we care about giving the correct one.
I do have to give you points though for understanding that evolution only talks about life and not the solarsystem forming, which seems to be a common missunderstanding. You just have to realize that species and life are just as seperate in theory as take for example..
A murder case.
You have a dead victem and you find out what killed them and how long they been dead.
Now you have the cause of death.
You do not know who killed the victem. But that is seperate from knowing how the victem died. No dective is going to say "well I dont know who killed the victem so i cant possibly know if the knife in the chest was the cause"

Note to self, type faster -.-
