@Sheril Yes, Sheril, it's absolutely correct! Before it was discovered that the Earth was like a Sphere, ancient people believed that the Earth was Flat & if anyone crossed the edge, he will fall flat in Space! When Galileo made a statement that the Earth was round, he was compelled to drink poison as his statement was considered blasfamouse against religious belief of that time!🤔😜

@SKV @Sheril
This is not correct. The Earth has been known to be round since Classical times, and this has always been accepted by mainstream Christianity.

@timglauert @Sheril Small Correction. I have discovered in Google/ Wikipedia posted below:-
Aristotle (384-322 BC) was among the first to recognize the fact of our planet being a round sphere. He observed lunar eclipses and noticed that only a round sphere could imply a circular shadow. This astronomical observation was confirmed by general observations made at sea.
My apologies please.😜🙏

@timglauert @Sheril .Another correction about Galileo:-
For his heresy in claiming that Earth orbits the Sun, Galileo was sentenced to life imprisonment by the Roman Catholic Church in 1633. He was not tortured or executed. He served his sentence under house arrest and died at home in 1642 after an illness. My apologies again.🙏

No need to apologise, it is a very common misconception. It is used by Flat Earthers to erroneously claim that the Catholic Church once supported Flat Earth.

@timglauert @SKV @Sheril The Catholic Church did, however, declare Galileo's assertion that the Earth revolves around the Sun (and not the other way around) to be heresy. Galileo was forced to live out the rest of his days under house arrest.

@SKV @Sheril well, actually... No one serious considered earth flat after 500B.C. https://oceanservice.noaa.gov/education/tutorial_geodesy/geo02_hist.html

Galileo's heresy was earth revolving around sun.

NOAA National Ocean Service Education: Global Positioning Tutorial: The History of Geodesy

Throughout history, the shape of the Earth has been debated by scientists and philosophers. By 500 B.C. most scholars thought the Earth was completely spherical. The Greek philosopher Aristotle (384-322 B.C.) is credited as the first person to try and calculate the size of the Earth by determining its circumference (the length around the equator) He estimated this distance to be 400,000 stades (a stadia is a Greek measurement equaling about 600 feet). With one mile equal to 5,280 feet, Aristotle calculated the distance around the Earth to be about 45,500 miles (Smith, 1988).

People knew earth was round well before Galileo's time. His trial was because his observations of Jupiter's moons led him to believe Earth went round the Sun, contradicting Catholic dogma at that time. And he was put under house arrest after recasting, not forced to drink poison.
