But these lakes and rivers are not convex over the visible and testable distance in which a 1 to 8 inch drop is supposed to exist in one mile.
Dave, an 8in drop over a distance of 63,360in (1mi) is not going to be very noticable. In fact, unless you can perceive a drop of 1/7920th of a mile at a distance of a mile away, you're not going to be able to see the curve from ground level.
Gravity is imagined "holding" oceans and lakes and rivers in place so that they cannot move to level / flat in a long not visible distance yet we find in every case in the short visible distance that they do move to level with no visible curve. Because we see water moving to level in a mile distance, and every mile over every mile of every longer distance, we must conclude there is no curve or drop other any long distance.
Again, Dave, unless you can see a 1/7920th of a mile drop at a distance of one mile away, you're not going to be able to see the curve of the earth at ground level.
Dave, there are 63,360 inches in 1 mile. 8 inches is not that much of a drop after one mile, neither is
This is the decimal result when you divide 8/63360 (or reduced to 1/79720):
0.000126262626262626262626262626262626262626...(number continues infinitely)
That is 0.012626262626262626262626...% of a mile. You simply can't see that kind of a difference 1 mile away. That's why people like you make the claim that the earth is flat, because you can't comprehend the scale of the earth.
Dave, I already said that even if gravity didn't exist, and only buoyancy/density determined whether something goes up or down, then objects would STILL only go up to the sky or down towards the CENTER of the globe earth.
Dave, get out a pencil and paper (or if you can, build what I'm about to describe), and draw a large circle for me, and put a dot in the middle. Yes, please do this, I want to see if you're capable of comprehending how gravity works (even if we don't know what it is or what causes it).
Now draw 20 lines out from the center (preferably not straight across the center) of the circle, and make sure they're drawn neatly and equidistant from each other Then draw a short perpendicular line (a tangent) on the edge of the circle where the lines meet the circle, then draw an arrow on the outside of the tangent lines pointing towards the center of the circle.
You may want a compass (no, not the directional compass, what you use for drawing circles) and a ruler and maybe even a protractor.
Ok, now that that's done, we're gonna test your imagination for a bit. Imagine that each of the tangent lines are magnetic bars on sliders that can move in and out from the center of the circle, but have a tendency to slide away from the center of the circle because they are arranged positive to positive and negative to negative ([-+][+-][-+][+-][-+][+-][-+]) all the way around, and that each of the lines inside the circle are rubber bands that pull in the direction the arrows are pointing.
The rubber bands represent gravity, and the magnetic bars represent water molecules.
What do you think happens when the bars are allowed to slide freely on their rails? they find their own distance from the other magnets, right?
In that same way, (though not through magnetism,) water finds its own level on a spherical planet.
That's no different than saying we don't see evolution in the short span of time but it is occurring in the long term that we cannot see.
Dave, using your reasoning, you're the one making the claim, "because we can't see a curve (like evolution (which again, I DO NOT believe happens)) therefore it must not be curved (therefore no evolution happens)."
That's called an argument from silence, or an argument from ignorance, both of which are logical fallacies.
Both the evolutionist and the globists argue from what is invisible, the one from the invisible distance of time the other from the invisible distance of miles. Both contradict what we see in the short term both in time and miles.
Dave, I'm pretty sure that I've asked you this before, but could you please stop lumping round earth creationists in with evolutionists?
As for what you said, No, Dave, round earth creationists DO NOT argue from what is invisible. We take measurements, make calculations, and prove our work. You on the other hand have provided nothing but hand-waving and just so arguments, along with plenty of videos which most people will never watch, because the premise is illogical.
