For instance, there was no free oxygen in the atmosphere or dissolved in the oceans.
The conditions now are not suited to abiogenesis - organic molecules that form will get consumed or broken down.

There is no drive toward complexity per se.
If you start with single-celled organisms, where is there to go except more complex?
Many organisms are very simple and have been so for billions of years.

Hi thanks you got what I meant. Yes I have heard and considered that argument. But haven't scientists duplicated the conditions and made "primordial soup" and flashed lightning at it and it just hasn't happened? It's an area of research I am very interested in. Why can't we make new life? It should be easy Angry

Why should it be easy? It should, in fact, not be easy.
If it were easy, life would have started many times, possibly in many ways with different chemistries. But it doesn't look like it did.

We have tried to reconstruct the conditions and we have been doing those experiments in a few bottles for a few decades. Nature had the whole earth for millions of years.

Quote:If there is no drive towards complexity why are we not still one celled organisms? They are extrordinarily successful. Things don't change unless they have to. Why did we not stop at being insects? They are all over the planet and incredibly adaptable. It's quite incredible really that we have evolved arms and legs and brains to be able to manipulate our environment. I am not a creationist but it does look like evolution has an objective. I believe it is a question worth answering.

Like I said - if you start with one cell there's nowhere to go but more complex.

There is no evidence of purpose, direction, goals, or foresight in evolution.
In fact, the evidence indicates that evolution is blind and purposeless.


You should read about evolution. I suggest:

The Blind Watchmaker, R. Dawkins
Climbing Mount Improbable, R. Dawkins
River Out Of Eden, R. Dawkins
The Greatest Show on Earth, R. Dawkins
The Ancestor's Tale, R. Dawkins
Skepticism is not a position; it is an approach to claims.
Science is not a subject, but a method.
