No. Yours isn't a "theory" and it doesn't make predictions, for reasons already given and unaddressed by you.
You still don't know what a theory is, huh? Here, I'll give some basic definitions that you probably should have learned at some point, at least if you had finished high school. I'll even pull them directly from Merriam-Webster to avoid any possible confusion.
science - knowledge or a system of knowledge covering general truths or the operation of general laws especially as obtained and tested through scientific method b: such knowledge or such a system of knowledge concerned with the physical world and its phenomena : natural science (there are other definitions, but this one is the obvious choice for this discussion)
theory - 1: the analysis of a set of facts in their relation to one another
2: abstract thought : speculation
3: the general or abstract principles of a body of fact, a science, or an art <music theory>
4 a: a belief, policy, or procedure proposed or followed as the basis of action <her method is based on the theory that all children want to learn> b: an ideal or hypothetical set of facts, principles, or circumstances ?often used in the phrase in theory<in theory, we have always advocated freedom for all>
5: a plausible or scientifically acceptable general principle or body of principles offered to explain phenomena <the wave theory of light>
6 a: a hypothesis assumed for the sake of argument or investigation b: an unproved assumption : conjecture c: a body of theorems presenting a concise systematic view of a subject <theory of equations>
synonyms see hypothesis
hypothesis - a tentative assumption made in order to draw out and test its logical or empirical consequences (again there are others, but this is the only one that applies)
model - 11: a description or analogy used to help visualize something (as an atom) that cannot be directly observed
12: a system of postulates, data, and inferences presented as a mathematical description of an entity or state of affairs ; also : a computer simulation based on such a system <climate models>
Now that I no longer need to assume that you're acquainted with the relevant terminology, we can begin the rest of your education. I'll restate my proposal for your convenience. I propose two theories:
1. The universe started billions of years ago as a big bang. Things have evolved since this time on cosmological scales as predicted by the theory of relativity and its related mathematical models of cosmic mechanics.
2. The universe started 10,000 years ago at an initial state identical to that predicted for this time point in the previous theory. Things have evolved since this time on cosmological scales as predicted by the theory of relativity and its related mathematical models of cosmic mechanics.
As I have already stated, it is clear that, since both of these theories are governed by the same field equations (i.e. mathematical models of cosmic mechanics), they will always give identical predictions from the same initial state. Therefore, the predictions of theory #2 are identical to theory #1 from 10,000 years ago onward forever.
