Ancient China had the best equipments and the largest army among your list. Remember Huns who raped Romans so bad? Well, guess what...It was Han(Ancient Chinese empire) that raped Huns...and Huns had to run away for their survival and Europe was where they tried to settle down

Romans had around 340,000 soldiers at their extent.
Han had around 600,000 soldiers at their extent.
.
Han conquered bigger land than Romans did.

Some say China was built in a peaceful way...
The truth is here, let me show you.

1)400 years of warfare(they call it autume-fall century because there was always war going on during autume and fall) - famous Sun-Tzu wrote his the best military guide ever written

2)Chin unites China(Chin killed more than 800,000 soldiers of enemy states during its quest)

3)Cho-Han struggle(war killed more than 50% of Chinese at that time)

War builds powerful army and talented generals...If you studied Chinese history, then you would know Ancient China had most of best generals in Asian history...

So a misunderstanding like 'Caesar Rules!' doesnt really prove anything. Because I can mention more than 10 generals who at least equres Caesar in battlefield. They..
1.experienced a lot more battles than Caesar(of course, they won most of it)
2.in terribly outnumbered situation
(General Bai Qi took out 400,000 veterans with 75000 soldiers who have no experience of real war..
Sun Bin, a grandson of Sun-Tzu, defeated 3 times bigger enemies marching from 3 direction surrounding him with losing only 5% of the army.
Huo Qubing invaded Huns and wiped them out of Asia at age of 24)

And one more thing...unlike Romans, China had cavalry units with saddles. Roman cavaly had to ride bareback...so whose cavalry is stronger? Chinese, of course...

So I say Ancient China would win definitely

Religion

The religion of ancient Egypt was polytheistic and centered around the divinity of the ruler and the eternity of the soul. The Chinese were polytheistic with the addition of ancestor worship. Over time, these beliefs were sometimes blended with Taoism, Buddhism or Confucianism. Funeral Customs

In Egypt, people were buried with thought to preservation, as they believed that the dead would be able to use their bodies in the afterlife. Chinese burial
