4. what were some of the general religious practices of each american indian (mayans, incas, and the aztecs) civilization?

Mayans believed in multiple Gods especially the corn God , they even squished their heads to be shaped like corn that’s how much they worshipped him .. Aztecs sacrificed people as a religious practice (even ate them) and played deadly games that results on the winners having to be the sacrifice ... they just did a lot of human sacrifices and eating of humans fun fact : they sacrificed sooo much that the temples that they had created which were made of clay of some sort (and brown colored) was so bloody that from a distance you would think it was painted red

Ship building industry , good luck : )
