Contingent being exists=Principle of Existential Contingency (Bc exists)

Not everything that exists is necessary. For change is real, that is, at least some being(s) really change. And a Necessary Being cannot change in its being. (This does not mean there can be no change in external relations with another being. It simply means there can be no internal change in its being. When a person changes in relation to a pillar, the pillar does not change.) For its being is necessary and what is necessary in its being cannot be other than it is in its being. And all change in being involves becoming something else in its being.
But it is evident that I change in my being. I change from not being to being. By "I" is meant the self-conscious individual being call myself. (This is not to claim that all the parts or elements of my being are not eternal. There are good reasons to believe they are not because usable energy is running down and cannot be eternal, but this is not point here.) This "I" of consciousness around which these elemental parts of matter come and go, is not eternal. This is clear for many reasons.
First, my consciousness changes. Even those who claim they are eternal and necessary (namely, that they are a Necessary Being, God) were not always conscious of being God. Somewhere along the line they change from not being conscious they were God to belong conscious they were God. But a Necessary Being cannot change. Hence, I am not a Necessary Being. Rather, I am a contingent being. Therefore, at least one contingent being exists. Everything is not necessary.
Further, there are other ways to know one is contingent. The fact that we reason to conclusions reveals that our knowledge is not eternal and necessary. We come to know , But no necessary being can come to know anything. It either eternally and necessarily knows everything it knows or else it knows nothing. If it is a knowing kind of being, then it necessarily knows, since it is a necessary kind of being. And a being can only know in accordance with the kind of being it is. A contingent must know contingently and a Necessary Being must know necessarily.  But I do not know all that I can know eternally and necessarily. Therefore, I am a contingent kind of being.
Therefore, one necessary, eternal, uncaused, unlimited, rational, personal and moral being exists.

Adaptation and science, Part Three

 Adaptation: 
 A physical trait or behavior due to inherited characteristics that gives an organism the ability to survive in a given environment.

Consider a woodpecker pair off the Ark. The pair may contain genes (information) for long and short beaks. As the birds spread out into the lush new world growing in the newly deposited soil, they produce offspring that contain both long-beak and short-beak genes. (Although the actual control of beak growth is complex, we will assume that long is dominant over short for this simplistic example.) Areas populated by trees with thick, soft bark would tend to select for woodpeckers with longer beaks. Areas where the bark thinner and harder would tend to be populated by woodpeckers with shorter beaks. Two new species, with slightly different adaptations, could arise if the two populations were geographically separated. The population of short-beaked woodpeckers would have lost the information for long beaks. No more long-beaked woodpeckers would be produced without a significant addition of genetic information affecting the beak length. The long-beaked woodpeckers would still have the ability to produce short-beaked offspring, but they would be less able to compete and those genes would tend to decrease in frequency in the population. Due to their isolation, two new species of woodpecker would develop, but within their kind. Observable science supports this type of subtle change within a kind but not molecules-to-man evolution.
