Its a proven scientific fact that the Earth is like, a trillion years old, and in the Bible, it does say that God's time is seperate from our own]
You're...actually as wrong as the young-earth creationist. Earth is about 4.6 billion years old. The sun is slightly older. The universe--as we observe it today--is around 13.75 billion years old.
There are theories, sure, but these theories must ignore contrary data such as rates of eroding coasts (there would be no land above water if the earth was really millions of years old),
I'll take "active geology" for 100, Alex.
First, sea level fluctuates. Second, the earth's crust is being pushed up in many places around the world, all the time, by forces from beneath. It's happening at this moment. Third, new crust is being created at mid-ocean ridges and at volcanic events. These are all directly confirmable, and it ensures that there's always some land somewhere above sea level. And coast lines change, even on human timescales.
sun depletion
Yes, the sun is running down. Very...very...very slowly, because it's about 332,950 times more massive than Earth. That's a lot of fuel to burn through. We know about how fast it's burning fuel, too.
supernovas
Supernovas confirm the speed of light has undergone no drastic change in value over the age of the universe.
animal/human populations
The NCSE thinks your argument is invalid:
Whitcomb and Morris estimate conservatively that pre-flood families had six children (c=3) and that generations averaged ninety years (1961, pp. 25-26). Morris claims the decay of the magnetic field gives an "outside limit" of ten thousand years for the age of Earth (1974, p. 158). The oldest reported date of the flood is sixty-three-hundred years ago (Morris, undated). Therefore, the population at the time of the flood must have been at least:
2(3)41 = 7.2946 x 109
If one cares to work out the population density, it comes out to be over thirteen thousand persons per square foot for the entire earth's surface, or about 0.01 square inch per person. If the flood occurred only four thousand years ago, as suggested in Scientific Creationism, the mass of humanity at that time would have exceeded the mass of the earth.
It is interesting to examine this figure of 7.2946 x 1019 persons in view of Morris' assertion that the human fossil record for evolution is incredibly deficient (1974, p. 169). Since, according to creationist calculations, at least "3000 billion people would have lived and died . . . in the past million years," if evolution is true, there should be far more evidence in the fossil record. Yet the pre-flood population must have been over 24 billion times as great, and we are offered only "Paluxy man," Carboniferous "human footprints," and a few others as evidence of this mass of humanity.

unstable carbon levels in the atmosphere
Not sure what you mean by "unstable" here--do you mean "radioactive," or do you mean "fluctuating?" Because neither of these is a problem for an old earth in the way you think they are.
and a host of other things.
You probably should have named them.
Available data points to an old planet. None of the data you sloppily cite says what you think it says.
