Of course I acknowledge that I believe differently than you. I have been making that clear for the entire conversation. I certainly wouldn't want anyone to think I agree with someone who believes in woo but doesn't believe that stars exist.
What a silly comment. I believe the sun is real. Why? Well among other things, if I stay out in it long enough my skin turns red. Also, I can see it. Also, I can see shadows.
On the other hand, you argue that the sun didn't exist until there were humans to see it.
You haven't addressed how humans came into existence to see the sun if the sun was not there before humans.
That is why I said:
You are not aware that we are doing philosophy. So how do you justify, that you know, that the sun exists?
I believe that my experiences of the sun matches my general experiences and I do believe that they are real, because I believe God is fair and that there is no evil demon tricking me.
I make the assumption that I can trust my existence, because God is fair in regards to this universe not being a case of an evil demon, a Boltzmann Brain, a computer simulation or what not.
So I can't see that the universe is fair in this regards, I have place a mental property on it. It is fair and thus not physical nor natural, but rather a deity, i.e. God.
Here is a modern version of Descartes' problem of how we can trust our senses:
Simulation hypothesis - Wikipedia
"Many works of science fiction as well as some forecasts by serious technologists and futurologists predict that enormous amounts of computing power will be available in the future. Let us suppose for a moment that these predictions are correct. One thing that later generations might do with their super-powerful computers is run detailed simulations of their forebears or of people like their forebears. Because their computers would be so powerful, they could run a great many such simulations. Suppose that these simulated people are conscious (as they would be if the simulations were sufficiently fine-grained and if a certain quite widely accepted position in the philosophy of mind is correct). Then it could be the case that the vast majority of minds like ours do not belong to the original race but rather to people simulated by the advanced descendants of an original race."
So before you establish that you use your senses to see the sun, I am going to ask as a skeptic, how you know that you can trust your senses.
And that leads here:
"
Naturalism is the implicit philosophy of working scientists.
[47] The following basic assumptions are needed to justify the scientific method.
[48]
- that there is an objective reality shared by all rational observers.[48][49] "The basis for rationality is acceptance of an external objective reality."[50] "Objective reality is clearly an essential thing if we are to develop a meaningful perspective of the world. Nevertheless its very existence is assumed." "Our belief that objective reality exist is an assumption that it arises from a real world outside of ourselves. As infants we made this assumption unconsciously. People are happy to make this assumption that adds meaning to our sensations and feelings, than live with solipsism."[51] Without this assumption, there would be only the thoughts and images in our own mind (which would be the only existing mind) and there would be no need of science, or anything else."[52]
- that this objective reality is governed by natural laws;[48][49] "Science, at least today, assumes that the universe obeys to knoweable principles that don't depend on time or place, nor on subjective parameters such as what we think, know or how we behave."[50] Hugh Gauch argues that science presupposes that "the physical world is orderly and comprehensible."[53]
- that reality can be discovered by means of systematic observation and experimentation.[48][49] Stanley Sobottka said, "The assumption of external reality is necessary for science to function and to flourish. For the most part, science is the discovering and explaining of the external world."[52] "Science attempts to produce knowledge that is as universal and objective as possible within the realm of human understanding."[50]
- that Nature has uniformity of laws and most if not all things in nature must have at least a natural cause.[49] Biologist Stephen Jay Gould referred to these two closely related propositions as the constancy of nature's laws and the operation of known processes.[54] Simpson agrees that the axiom of uniformity of law, an unprovable postulate, is necessary in order for scientists to extrapolate inductive inference into the unobservable past in order to meaningfully study it.[55]
- that experimental procedures will be done satisfactorily without any deliberate or unintentional mistakes that will influence the results.[49]
- that experimenters won't be significantly biased by their presumptions.[49]
- that random sampling is representative of the entire population.[49] A simple random sample (SRS) is the most basic probabilistic option used for creating a sample from a population. The benefit of SRS is that the investigator is guaranteed to choose a sample that represents the population that ensures statistically valid conclusions.[56]"

You apparently as least use 1 and 2.
I do share 1. I just don't share 2.
