I agree with Paul; "God" is the obvious conclusion for any reasonably thoughtful person. But this in way no entails that everyone on the Internet is reasonably thoughtful, or that they will be be able (or willing) to follow even simple arguments.
This is a delusional argument.. It's like trying to say people that reject that are magically not reasonably "thoughtful" people. Dogmatic games of manipulation are not worth anything, and nor do they have any real value in an honest debate.
And Just so people can get a better understanding of omniscience, you can reference this simple demonstration:
The Omniscient Creating Knowledge Problem
There are arguments suggesting that the true cause of all causation can not be that which is slave to require a cause for it's own existence, or even to know of it's own existence. Thus it is said that one can not know how to create knowledge into existence because it is slave to require it as a base of inquiry to itself. This would then violate the premise of such an entity being omniscient since it can not know how to create knowledge. This is especially true when we understand that Knowledge is a body of information to which is the base of inquiry. It comes down to the principle of all principles that are seen to govern the base of all knowledge, and those that which require knowledge to be all that which they are. It's a question of where and how does something as complex as consciousness arise and exist. Here it is said that consciousness is a product to which can not exist without the base principles of causation, or to where consciousness is too complex and can not exist without cause. This comes from those exploring the idea that things to which are not conscious would require less cause to exist than those things to which are conscious. These principles have been argued in regards to information theory by those who see information itself as the cause and substance to everything. As referenced here:
Information: The Material Physical Cause of Causation But lets further explore Omniscience below and give a prime example of why it's a delusional concept.:
Omniscience:
(pronounced /ɒmˈnɪsiəns/)[1] (or omniscient point-of-view in writing) is the capacity to know everything infinitely, or at least everything that can be known about a character including thoughts, feelings, life and the universe, etc. In monotheism, this ability is attributed to God. The God of the Bible is often referred to as "The Great I Am," among other similar names, which also incorporates his omnipresence and omnipotence. This concept is included in the Qur'an, where God is called "Al-'aleem". This is the infinite form of the verb "alema" which means to know. In Hinduism, 'omniscient' or 'all-knowing' (IAST: sarva-gya; Sanskrit: सर�वज�ञ )[2] 'omnipotent' or 'all-able' (IAST: sarva-samartha; Sanskrit: सर�व समर�थ) and 'omnipresent' or 'all-pervading' (IAST: sarva-vy�pi; Sanskrit: सर�व व�यापि) are attributes of divinity or spiritual 'perfections' (Sanskrit: siddhi). In latin, omnis means "all" and sciens means "knowing"
Omniscient Solipsism from a Designers Perspective:
(This as if you are the Omniscient Entity about to design and create something into existence. Such as a human being)
1. I'm Omniscient
2. I have an idea of something I want to build, construct, or make existent.
3. I know infinitely everything about this thing, person, or place infinitely before, and infinitely after I have constructed it, or even thought of it.
4. I would know in my design everything it will infinitely ever do.
5. I would know everything about my design's essence or being to the point of actually, and literally being that of my design (object, entity, thing, or place) in every infinitely literal way. (and we must pay close attention to the term infinite)
6. I would know all the above infinitely in the past, present, and future.
7. This thing I designed would only be able to do what it's was designed to do, and what I already infinitely know it will do, even to the point of it actually being literally me, and literally me doing all those things myself in every infinite way imaginable.
8. Even if I wanted to state that I am only omniscient to which is knowable, 5, 6 (past, and present), and 7 would all be knowable. Omniscience would translate to I, the said entity being existence itself in the best case possible, or everything that is existent in every infinite way.
Thus we can conclude such a concept of an Omniscient entity to be likely nothing more than a logical fallacy..
Especially if we want to retain our individualism
