By assuming that what we see today will be the same tomorrow and in the future. We assume that gravity will still behave the way it behave today and in the future. We assume that our assumptions can be tested and verified. We assume that life had a beginning. Many, many assumptions are made every day that can not be tested and verified.
Yes, they can. We have substantial empirical evidence that gravity will operate tomorrow as it has done for the thousands of years humans have been keeping record, and for the millions and billions of years we can analyse from remnants of the past. This is not an assumption, this is an extremely well-evidence scientific theory.
As for the origins of life, that's not an assumption either, as we also have substantial empirical evidence to support the proposition that life had a beginning - first from the plethora of geological evidence that there was a time
without life, and second from all the evidences that support evolution.
As for the far distant future where even the most undetectable and incrimental change to physical constants would make itself apparent, science is more than capable of acknowledging that. Astronomers often debate and experiment whether or not the cosmological constants are changing, if they could even change, and what that would mean. It is not an assumption, it is a theory like any other: based on hard, empirical data and entirely open to falsification.
Methodological assumptions The two methodological assumptions are universally acclaimed by scientists, and embraced by all geologists. Gould further states that these philosophical propositions must be assumed before you can proceed as a scientist doing science. "You cannot go to a rocky outcrop and observe either the constancy of nature's laws or the working of unknown processes. It works the other way around." You first assume these propositions and "then you go to the out crop of rock."

- 'Uniformity of law across time and space: Natural laws are constant across space and time.[18]
- Uniformity of process across time and space: If a past phenomenon can be understood as the result of a process now acting in time and space, do not invent an extinct or unknown cause as its explanation.[17]

You'd be well served to use sources other than Wikipedia. Nonetheless, in the same article, and from the same source no less:
"
Stephen Jay Gould's first scientific paper, Is uniformitarianism necessary? (1965), reduced these four interpretations to two, methodological and substantive uniformitarianism. He dismissed the first principle, which asserted spatial and temporal invariance of natural laws, as no longer an issue of debate. He rejected the second as an unjustified limitation on scientific inquiry, as it constrains past geologic rates and conditions to those of the present. So, uniformitarianism was unnecessary."
Gould himself rejected uniformitarianism.
"
The current consensus is that Earth's history is a slow, gradual process punctuated by occasional natural catastrophic events that have affected Earth and its inhabitants. In practice it is reduced from Lyell's conflation to simply the two philosophical assumptions. This is also known as the principle of geological actualism, which states that all past geological action was like all present geological action. The principle of actualism is the cornerstone of paleoecology."
In other words, two pragmatic assumptions prevail: first, that geological processes behave largely like they do today, and second, that extraordinary catastrophic events punctuate long periods of relative banality. These are easily testable, simply by observing the geological column, ice core samples, magnetic reservoir strips, etc. You also should be careful not to conflate geological uniformitarianism with cosmological uniformitarianism (geological uniformitarianism is the idea that there are long, gradual geological changes that operate much now as they did back then, punctuated with catastrophic events that induced rapid, but short lived, geological changes; it is the successor to geological catastrophism).
Metaphysics do. Forensic science is a good example in fact. Forensic scientists work with metaphysical assumption in doing their work consistently.

1. Introduction
The purpose of this article is to suggest research directions in
which the forensic identification sciences might proceed in order
to place their work on firmer scientific ground. The larger scientific
world is taking notice and insisting upon real science in forensic
identification (e.g. [1]).
First, however, we should remind ourselves of the core
assumptions that underlie conventional forensic identification,
and realize that they are based more on faith than on empirical
evidence, so that we can appreciate the need for improved research
and theory. These shortcomings are shared by all of the forensic
individualization sciences, certainly including forensic odontology.
I asked for specifics. Can you explain to me, in as much detail as possible, how uniformitarianism (as you've now changed your claim to) is present in the forensic sciences, and how they could not be performed without this alleged presumption.
I never claimed it was.
I'm fine.
Evidently not. Your initial definition of 'uniform' was from
here (post #140), and, surprised at this definition, I detailed it to you to make sure you understood what you were claiming (#141), and you agreed (#142). Now, however, instead of a broad uniform distribution of stellar material, you're changing your definition to geological/cosmological uniformitarianism - very different from your initial definition. Still, whatever floats your boat.
So I'm slinging mud by my statement? how about these:
Oh, and your claim that we can't have science without the supernatural is patently ludicrous. You might as well be claiming that we can't have pancakes without cows.
I don't think you know what that means. Nor does it seem that you understood my argument. I'll try to break it down:

I really can't be bothered to go into your personal issues with other posters. As I said, I simply want a civil exchange of ideas. Can we have that, please?
