Now the whole earth had one language and the same words. And as people migrated from the east, they found a plain in the land of Shinar and settled there. And they said to one another, “Come, let us make bricks, and burn them thoroughly.” And they had brick for stone, and bitumen for mortar. Then they said, “Come, let us build ourselves a city and a tower with its top in the heavens, and let us make a name for ourselves, lest we be dispersed over the face of the whole earth.” And the Lord came down to see the city and the tower, which the children of man had built. And the Lord said, “Behold, they are one people, and they have all one language, and this is only the beginning of what they will do. And nothing that they propose to do will now be impossible for them. Come, let us go down and there confuse their language, so that they may not understand one another’s speech.” So the Lord dispersed them from there over the face of all the earth, and they left off building the city. Therefore its name was called Babel, because there the Lord confused the language of all the earth. And from there the Lord dispersed them over the face of all the earth (Genesis 11:1-9).
Marduk: Originally, he seems to have been a god of thunderstorms. A poem, known as Enuma elish and dating from the reign of Nebuchadrezzar I (1119–1098 BCE), relates Marduk’s rise to such preeminence that he was the god of 50 names, each one that of a deity or of a divine attribute. After conquering the monster of primeval chaos, Tiamat, he became Lord of the Gods of Heaven and Earth. All nature, including humanity, owed its existence to him; the destiny of kingdoms and subjects was in his hands.
Marduk’s star was Jupiter, and his sacred animals were horses, dogs, and especially the so-called dragon with forked tongue, representations of which adorn his city’s walls. On the oldest monuments Marduk is represented holding a triangular spade or hoe, interpreted as an emblem of fertility and vegetation. He is also pictured walking or in his war chariot. Typically, his tunic is adorned with stars; in his hand is a sceptre, and he carries a bow, spear, net, or thunderbolt. Kings of Assyria and Persia also honoured Marduk and Zarpanitu in inscriptions and rebuilt many of their temples.
Marduk was later known as Bel, a name derived from the Semitic word baal, or “lord.” Bel had all the attributes of Marduk, and his status and cult were much the same. Bel, however, gradually came to be thought of as the god of order and destiny. In Greek writings references to Bel indicate this Babylonian deity and not the Syrian god of Palmyra of the same name. (Brittanica).
The ziggurat (including undoubtedly, the one in Genesis 11) was a portal which served as a connecting link between heaven and earth. They are considered the earliest known pyramids (which also served as portals to interdimensional realms in the Americas as well as in Egypt and Sudan). The idea that the tower of Babel was a tower that would reach the heavens was much like the language that was used for other towers that were built in that area: Stairway to Pure Heaven (Sippar), House Binding Heaven and Earth (Nippur), Temple Linking Heaven and Earth (Larsa), Temple of the Foundation Platform of Heaven and Earth (Babylon). The purpose of such structures was to provide a shrine for the gods.
The tower's "top in the heavens" used spiritual matters to manipulate the people. This expression uses spiritual wording. The top of the tower spiritually reached into the heavens, home of the gods. The earliest built tower with similar purpose, the Tepe Sialk Ziggurat, featured a shrine for god at its top. This Ziggurat, at Kashan, Iran, is almost due east of Baghdad and nearby Babylon. The migrating people, later building Babel, brought the ideas behind Sialk's design with them to Mesopotamia. This part of their belief system regionally continued after Babel. They believed the tower's top was a gateway to the gods. Humanity's religion is always trying to reach into heaven (Romans 10:6). Christianity is different because God came to us (John 3:13). (MacDonald, Brent 2016).
The tower was built to rise up, into the very throne of God. In this case, they were not building a shrine unto God, but to "make for themselves a name," so as to establish unity and strength, without God. It is said that YHWH, whose name was known this time was not being reverenced, but invaded (in a sense), as they were building a tower to reach God (in a spiritual sense), without the aid of God. If this "invasion" claim is true, it is similar to (but is not) the invasion of Lucifer in Isaiah 14:13).
And the Lord came down...(v5).
From this time forward, God's people have had to deal with Babylon who will not fall until the fulfillment of its falling in Revelation 18. If Babylon was here from the beginning, and destroyed at the end, then we are clearly contending with it now.
Interdimensional portals are not symbolic. They are real. As they did this in ancient Babylon, it is being done today through occult magick.
