Are you born agnostic or atheist?

[Faith No More]

Here is the definition of agnostic from dictionary.com

2.a person who denies or doubts the possibility of ultimate knowledge in some area of study.

Here is the definition from thefreedictionary.com

1. a. One who believes that it is impossible to know whether there is a God.
b. One who is skeptical about the existence of God but does not profess true atheism.
2. One who is doubtful or noncommittal about something.

Here is the definition from merriam-webster.com

1. a person who holds the view that any ultimate reality (as God) is unknown and probably unknowable; broadly : one who is not committed to believing in either the existence or the nonexistence of God or a god
2. a person who is unwilling to commit to an opinion about something <political agnostics>

If one takes into consideration these definitions, then a person cannot be born an agnostic, because a prerequisite for each of these definitions is that some thought has been put into the subject. Personally, I think the better definition for agnostic is without knowledge, but this is some food for thought.
