Why is there a distinction? The mechanisms are the same, the effects are the same. Even down to the genetic level. Like I said: There is no difference at all between micro-evolution and macro-evolution. None at all. They both document traits that are passed on from parent to child. Traits in successful parents are passed on, and can be tracked at both the physical level and the genetic level.
Science is aggressively seeking answers. Of course, you're looking at it the wrong way. They haven't decided on the culprit. Evolution is not a person or a movement. It's simply a description of an observed process. In other words, in your criminal case, when police say "evolution has taken place", they mean the "victim has been murdered", and all that's left is to find out why and how it happened.
Saying: "Maybe it wasn't evolution."
is like saying:
"Maybe there wasn't a murder. Maybe this corpse appeared out of thin air and dropped onto the carpet below."
Mustangs are hardly the oldest breed/species of horse.
Evolved, yes. Speciated, as in completely and utterly unable to mate with related species... not yet. Horses diverged from zebra around 4-5 million years ago.
Why would it support Creation? And we could have hardly had a hand in the death of the Dinosaurs, since humans weren't around sixty five million years ago.
Evolution doesn't care who or what decides upon which members of a species reproduces. It only states that those members that reproduce, for whatever reason (look up the concept "Survival of the Tastiest"...) will pass on their traits.
Scientists don't pull numbers out of thin air, but consider the environment in which the fossil was found, in which it was created and the rock strata where it was found in assessing the accuracy of carbon-dating. While we could be off by a couple of mega-years on some of the oldest fossils, there's little chance a fossil dated at over a hundred million years old, found in rock layers of that time, is really just a few thousand years old.
The carbon-dating process isn't only used on fossils, but is also used to date historical artifacts, and can be quite accurate, as such.
1. Are we sure the first life form was the first life form, or merely the first to reproduce? As said... replicating molecules existed before replicating cells.
2. How sure are you we aren't simple? How sure are we that our apparent complexity and consciousness isn't merely an artefact of the biological processes that make up our being?
There are already successful organisms that are relatively simple. Bacteria. Organisms that aren't successful at all die out. Organisms that are only successful in a limited sense must either become more successful or die out. Thus they develop new strategies of survival. Can't compete with all the other bacteria? Start eating other bacteria. Can't survive because you're being eaten? Become more mobile. Start living in colonies. Start living in mega-colonies. As a colony, start dividing work amongst components. These components for locomotion, these for eating, these for communication... etcetera... etcetera... until you get to us.
We're the misfits that weren't strong enough, weren't fast enough, weren't vicious enough, so we had to become smarter to survive. Along the way, we developed something called language, and intelligence.
(Of course, there's the whole catastrophism thing... extinction events like the asteroid that killed off all life bigger than rats during the Cretaceous... the Ice Age... cosmic radiation... but then, again... Evolution is blind... whoever survives, survives, for whatever reason they do so.)
The consciousness part... that's a mystery. But we're pretty sure that other animals have a form of consciousness and some really ancient ones even have intelligence (octopii and squid), but knowing where it exactly started is something we can't do until we know what it is in us that creates it.

But...the elephants, horses and dogs (I'm assuming you're talking about domesticated animals...although, the elephants are really all that domesticated) are all the result of human breeding. A better word for it would be "tampering."
Horses really haven't come all that far from the mustangs. In fact, the Mustang Reintroduction Program is going extremely well.
Mustangs are hardly the oldest breed/species of horse.
Dogs are the only real specie that's seen significant "evolutionary" change. And, again, it's not really evolution. You also answered your first question of "How long do you think evolution takes" with, "these species have evolved since man's been around."
Evolved, yes. Speciated, as in completely and utterly unable to mate with related species... not yet. Horses diverged from zebra around 4-5 million years ago.
I'm just not sure if you can count domesticated animals as "evolution" since it was the human race that domesticated them and ultimately changed them. Which, if that is evolution, then that should show you the impact man-kind has on the evolutionary change. I mean, if we can cause animals to evolve to become our obedient pets, then...that would more support the Christian creation story where God gives us dominion over the animals and the land. He gave us power to change and evolve them to suit our needs. Maybe the dinosaurs evolved into birds because we didn't like dinosaurs being the top of the food chain.
Why would it support Creation? And we could have hardly had a hand in the death of the Dinosaurs, since humans weren't around sixty five million years ago.
Evolution doesn't care who or what decides upon which members of a species reproduces. It only states that those members that reproduce, for whatever reason (look up the concept "Survival of the Tastiest"...) will pass on their traits.
Also....we really don't know how old the earth is. I've already said this. There isn't any accurate to tell how old it is, either. Carbon-14 dating is incredibly inaccurate and is dependent upon a lot of variables. Fossils would also probably be the most inaccurate candidates for carbon dating because to fossilize something requires a lot of sediment laid down really fast. And there's no way to tell how much carbon-14 was added or taken away from the fossil in the process. I think it would be interesting to develop away to test fossilization to determine how much it effects the carbon dating process.

I have two questions about evolution:
1. How was the first life form able to reproduce? Why did it not just live and die? Was there lots of life forms before the first life form that could reproduce that came into existence?
2. Why are we conscious? Why don't we just work like primitive computers? Wouldn't that be more successful, and more crucially, simpler?
(Okay, there are a few questions here, but they are all related two the two points.)
And just to make it clear, I'm not asking this to try to disprove evolution, I just want to understand.
1. Are we sure the first life form was the first life form, or merely the first to reproduce? As said... replicating molecules existed before replicating cells.
2. How sure are you we aren't simple? How sure are we that our apparent complexity and consciousness isn't merely an artefact of the biological processes that make up our being?
