Why first living beings were fully developed?!

 

Living beings that appeared on Earth half a billion years ago all had complex systems in their bodies. 

 A complex system consists of a large number of smaller components that are all interrelated to one another. Each component of this complex system has an individual task that it performs in harmony with other components. And at the same time, it is also in constant interaction with nearby structures. in order for the system to work, all its necessary components need to be present all together at once. absence of even one component can render the whole system useless.

The eye for example is one such complex structure, it is based on many small parts such as the cornea, conjunctiva, iris, pupil, lens, retina, optic nerve, and the visual cortex of the brain,  all these parts of the eye need to be present and functional to make the vision possible. The absence of even one of these parts can render the whole eye visionless. For example, if there is no retina, the light would pass through the lens but would not form an image. and If there is no lens, the light would not be focused to form an image on the retina. And if all exist but the optic nerve does not, then the signals for the formed image would not reach the brain to produce vision. all the components of the eye, therefore, need to be present and working at the same time for vision to be possible. This complexity is present in living beings down to a single cell and even at the fundamental level of protein within the cell. 

 but the widely accepted theory of evolution claims that living beings developed these complex systems by evolving from undeveloped life forms over the course of millions of years. fossil record which is true scientific evidence of what early lifeforms really looked like shows that the first animals that made their presence in the Cambrian seas 500 million years ago appeared suddenly with their complex systems fully developed. They had eyes, antennae, nervous systems, guts, predatory skills and defense mechanisms identical to those possessed by today's complex living beings. And they had no simpler or undeveloped forms of themselves existing before. So The presence of such complex systems in early animals already when they first appeared on Earth refutes the claims of gradual development. Living beings cannot go through the process of evolution because their complex systems require all their parts all at once, or they won't survive.

Darwin the founder of this theory, himself said that If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down

His theory of evolution has today been overthrown, just as he feared. Science has established the fact that such complex organs in cannot form step by step over millions of years. They need to be present as a whole for the system to work. And the only valid explanation for the appearance of living being with all their complex structures is that they have been created by a Creator, instantly and fully formed right from the moment they first appeared.
