"Zamzummims":
Deu 2:20 (That also was accounted a land of giants: giants dwelt therein in old time; and the Ammonites call them Zamzummims;
Deu 2:21 A people great, and many, and tall, as the Anakims; but the LORD destroyed them before them; and they succeeded them, and dwelt in their stead:
Others, "children of the giant", "sons of the giant":

There are two ways, the Ways of God, or the way of wickedness.
Another piece of the text to consider in the context of Genesis 6:4 are the words
"men of renown":
English:
"reknown" = Hebrew: "shem" "שֵׁם" [meaning: name, reputation, fame, glory, memorial, monument, stigma [a mark with which anyone is marked], notable, famous or infamous] [Strong's Concordance]
Compare to those in the camp of Moses, where the exact same words are used:
Num 16:2 And they rose up before Moses, with certain of the children of Israel, two hundred and fifty princes of the assembly, famous in the congregation, men of renown:
...or compare these passages which also deal with mankind alone:
Num 1:16 These were the renowned of the congregation, princes of the tribes of their fathers, heads of thousands in Israel.
Num 26:9 And the sons of Eliab; Nemuel, and Dathan, and Abiram. This is that Dathan and Abiram, which were famous in the congregation, who strove against Moses and against Aaron in the company of Korah, when they strove against the LORD:
1Ch 5:24 And these were the heads of the house of their fathers, even Epher, and Ishi, and Eliel, and Azriel, and Jeremiah, and Hodaviah, and Jahdiel, mighty men of valour, famous men, and heads of the house of their fathers.
1Ch 12:30 And of the children of Ephraim twenty thousand and eight hundred, mighty men of valour, famous throughout the house of their fathers.
...or compare to those who allow God to make them a great name, to those who make a great name for themselves:
[God makes the name great]
Gen 12:2 And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:
[Man makes the name great]
Gen 11:4 And they said, Go to, let us build us a city and a tower, whose top may reach unto heaven; and let us make us a name, lest we be scattered abroad upon the face of the whole earth.
Angels are nowhere explicitly mentioned in any of the passages, while all of the passages overtly speak of the lineage of sinful mankind, and their genealogy back unto Noah, back unto Adam.
