I'm open to believing that centuries-old scientists (most of whom where catholic and who described some variation of FE) were WAY more knowledgeable than our current, social media indoctrinated, public school educated, fast food eating, tv watching avg american. Seems to me that most people ignore FE simply due to intellectual laziness and also fear of the unknown.
All Catholic scientists starting from St. Bede (born 673 AD) believed that the earth is a globe. This includes other Doctors of the Church like St. Albert the Great, St. Thomas Aquinas, and St. Robert Bellarmine. The Catholic university system included teaching spherical earth as a main part of its curriculum throughout the Middle Ages. One can still read the most influential of the books used in these astronomy classes,
De sphaera mundi published in 1230
http://www.esotericarchives.com/solomon/sphere.htm .While sphaerical earth was never a religious dogma, it was accepted by all educated Catholics from medieval times onward, including the greatest minds in Christendom. This is my main reason for believing the earth is a sphere. (The idea that Catholics used to believe in Flat earth is a falsehood introduced into modern thought as anti-Catholic propaganda.)
Before the Medieval period we have records of a few Church Fathers who believed the earth was flat and a few who believed it was a globe. There was no consensus among the Fathers and most were silent on the subject. If anyone is interested in more details and references, please see my posts in the appropriate subforum.
