lol, if you can't dispute the evidence

It's obvious that you won't answer any science related questions regarding the footprints. Why is that? Is it because you know they're all frauds? Or is it because you don't bother to read the science.
who exactly is 65M years old - the humans, the dinosaurs, both or neither - the science, no bs.

There are those that embrace change and discovery. Their lives are enhanced and enriched by advances in technology and science. New discoveries are exciting.

The evidence shows that dinosaurs lived along side humans in our recent past. This is hard to believe because we were all raised and conditioned to believe dinosaurs are millions of years old, but we were never really given a good reason besides generic statements like "the fossil record". Yet our own ancestors in the past thousands of years have depicted dinosaurs consistently among all continents and cultures.
Abstract
The non-marine Horseshoe Canyon Formation (HCFm, southern Alberta) yields taxonomically diverse, late Campanian to middle Maastrichtian dinosaur assemblages that play a central role in documenting dinosaur evolution, paleoecology, and paleobiogeography leading up to the end-Cretaceous extinction. Here, we present high-precision U–Pb CA–ID–TIMS ages and the first calibrated chronostratigraphy for the HCFm using zircon grains from (1) four HCFm bentonites distributed through 129 m of section, (2) one bentonite from the underlying Bearpaw Formation, and (3) a bentonite from the overlying Battle Formation that we dated previously. In its type area, the HCFm ranges in age from 73.1–68.0 Ma. Significant paleoenvironmental and climatic changes are recorded in the formation, including (1) a transition from a warm-and-wet deltaic setting to a cooler, seasonally wet-dry coastal plain at 71.5 Ma, (2) maximum transgression of the Drumheller Marine Tongue at 70.896 ± 0.048 Ma, and (3) transition to a warm-wet alluvial plain at 69.6 Ma. The HCFm’s three mega-herbivore dinosaur assemblage zones track these changes and are calibrated as follows: Edmontosaurus regalis – Pachyrhinosaurus canadensis zone, 73.1–71.5 Ma; Hypacrosaurus altispinus – Saurolophus osborni zone, 71.5–69.6 Ma; and Eotriceratops xerinsularis zone, 69.6–68.2 Ma. The Albertosaurus Bonebed — a monodominant assemblage of tyrannosaurids in the Tolman Member — is assessed an age of 70.1 Ma. The unusual triceratopsin, Eotriceratops xerinsularis, from the Carbon Member, is assessed an age of 68.8 Ma. This chronostratigraphy is useful for refining correlations with dinosaur-bearing upper Campanian–middle Maastrichtian units in Alberta and elsewhere in North America.

I specifically said SCIENTIFIC evidence i.e. dating and stratigraphic evidence. You're posting opinions, not hard data.
Where's the hard data.

Here's a paper which discusses dating methodology. Can you date the human footprints using the same dating techniques and achieve similar results:

I hope you're prepared to write them a letter contesting their results.

There is not a single piece of evidence that shows any species of homo living with dinosaurs, let alone homo-sapiens.
I don't know about your education, but ours in the UK gives good, referenced geological data as one of the many reasons for believing dinosaurs are millions of years old. Much of the early fossil hunting was done in Great Britain or by Britons overseas, and is part of our rich history.

Carbon 14? That's like counting a packet of rice grains by only using 10 fingers. However many grains there are you'll only ever count 10. Are you serious? When you say things like this it just makes you look stupid. You must be aware of that, surely? What does radiometric dating say? Post that.
I've seen your links and I've seen your pictures. Did you have a look at the link I posted?
In your own words, explain how, with a high degree of certainty, they were able to know the initial concentration of the isotopic ratio that they were dating. Did they simply assume the initial ratio was 100-0? There is no full access, you're going to need to tell me this information if you want to discuss this paper further.

I don't have to tell you anything. The data speaks for itself. Isotopic ratios are used in medicine, physics, nuclear physics just to name a few. If all isotopes are wrong, then they're all wrong too.
You've made this ridiculous argument before. It didn't hold water then and it doesn't hold water now.
It's a complete asinine way of weaseling your out of the real science.
The next time you go to your doctor, make sure you tell him/her that you don't want anything to do with treatments that include isotopes. See how well that goes over. Maybe like a lead balloon?

That is not at all how radiometric dating works. Why don't you look up the decay chain of various isotypes and see how that can be used as an incredibly precise clock.
Instead of researching creation you should be researching nature. As I said before, I could be a much better creationist than you, and I don't believe in it.

People like Quad don't affect me with their insults. A nerve has been struck, and that's good. I also believe there are two different types of people in the world;
1) Those that embrace change and discovery. Their lives are enhanced and enriched by advances in technology and science. New discoveries are exciting.
2) Those that refuse to accept any challenge to their dogma. They are so entrenched in, and wedded to, their beliefs that any refutation is deeply personal and challenges their own identity. New discoveries trigger anxieties whether their belief system will be challenged yet again.
You see, I can have baseless opinions too.
lol it actually is exactly how it works.
They assume the initial isotopic ratio was 100-0, which is absurd because 100% pure samples never occur in nature.
Their assumption that the sample started as 100-0 is why all the age dates are so absurdly long ago.
You have never demonstrated that you know what you're talking about. Like Quad said, you resort to the opinions of others to defend your beliefs. This sort of blind belief is why you get so angry, because you have to respond with emotions in lieu of an actual logical defense.

100 percent is the initial amount it doesn't mean the entire rock was made of it. This just proves you dont understand the process. The typical way is whats called fission-track dating. You can tell whet the initial amount was y seeing what has decayed in your sample.
The only one making an assumption is you since you don't understand the process involved.
You have provided zero evidence yourself
Ill even give you a gimme some dinosaurs may have survived longer than we suspect or certain fringe scientists have claimed anyway. However, if they did it would likely be some of the avian-like ie raptor's as they adapted into birds.
