If you want to believe the Earth's flat, that's okay, I'm not a theologian but I've never heard that it's a heresy. People may think it's flat because it's still, and stillness may remind them of a flat surface, whereas a spherical shape may suggest to some in the subconscious a sense of "motion" ...
But water is naturally spherical itself, as it comes in particles as drops. When raindrops are falling, they tend to conform to the shape of pure space itself, which is spherical too. When they land on the surface of the Earth, they are traveling to the center. The center is equally related to all points on the surface in 3-D, and the only way that equal relation can be is if the Earth's a sphere.
How to prove that the center is equally related to all points on the surface? Because the direction called down that is perpendicular to water is the same angle and aspect for everybody around the Earth. It goes right below the feet in a universal way.
"Heavy" objects around the Earth like water fall down not because of Newtonian "gravity" but simply because they are too heavy to be supported by air.
Actually, as Tradman can demonstrate, the Early Church Fathers believed the earth was flat.

"The ancient Hebrews, like all the ancient peoples of the Near East, believed the sky was a solid dome with the Sun, Moon, planets and stars embedded in it."

Firmament is in the Bible 23 times.
Anyway, water drops are different from bodies of water which are always
LEVEL
If water is spherical then why do they use it to measure sea LEVEL
and why do builders use Water Levels?
If water is spherical that would really mess up their building plans wouldn't it?
Don't they use water because at rest it's always LEVEL?


It's been used for surveying land since ancient times:
Water Level Survey: Are You Smarter Than an Egyptian?Share this now!Are you smarter than an Egyptian? If you’re not using a Water Level Survey to determine the levelness of a house, then the answer to that question is “No!”
The History of the Water Level
Historians say that the ancient Egyptians were the first to use water levels as far back as 1100 B.C while building the pyramids. The bedrock was networked with narrow trenches, then filled with water. The Egyptians understood the physics of water, that water always resigns itself to be completely level, so the waterline was marked on all the trench walls, the protrusions were cut down, and the trenches re-filled with stone to create a level base.It’s amazing that something that was engineered over 3,000 years ago could still be one of the most accurate means of determining the levelness of a home or structure. JADE uses Water Level Surveys (or Manometers) today in our structural inspections. Though they deviate quite a bit from their original inventor’s design, they are still incomparable when it comes to accuracy.
A water level survey can give precise amounts and areas of floor sag or foundation settlement. The water level is superior to a standard four-foot level in this type of application because it shows relative elevation readings throughout the entire structure. This includes around corners and relative elevations from the front entry all the way to the rear bedroom. This information can be used to pinpoint areas in the crawlspace or basement that may have problems such as misaligned load-bearing walls, damage or improper construction such as long-spanning beams or joists.more:

use water to make sure it's LEVEL and you don't end up leaning over.
