Did Cain marry his sister after being kicked out?

Both Adam and Ish-shaw' (later Eve, after the fall) were created in the image of God.

God is spirit which is how they communicated with Him. But when Adam blew it …they lost that spirit connection Gen 2:17 for in the day that thou eatest thereof thou shalt surely die.

Physically, Adam lived for 930 years …but the spirit connection (image of God) was lost….that is what died.

From that time until Pentecost God had to come in some form of concretion ….or men of God had the spirit of God upon them conditionally to communicate with Him...... Today because of the redemption accomplished through Jesus Christ we have the spirit unconditionally when we accept Jesus as our savior. But we were not born in the image of God…we were born body and soul …natural man.

When you are born again because you receive the Spirit of the Father and Son, you are changed from your old self to the image of God.

No there weren't.

something that always puzzled me:

הֵן֩ גֵּרַ֨שְׁתָּ אֹתִ֜י הַיּ֗וֹם מֵעַל֙ פְּנֵ֣י הָֽאֲדָמָ֔ה וּמִפָּנֶ֖יךָ אֶסָּתֵ֑ר וְהָיִ֜יתִי נָ֤ע וָנָד֙ בָּאָ֔רֶץ וְהָיָ֥ה כׇל־מֹצְאִ֖י יַֽהַרְגֵֽנִי׃
Since You have banished me this day from the soil, and I must avoid Your presence and become a restless wanderer on earth—anyone who meets me may kill me!”

anyone who meets me may kill me!
^
isn't everyone his FAMILY?
or, is there someone else Cain doesn't know in person?

Yes, every potential killer is in his family. With the 8-900 year life spans and every man begetting sons & daughters, Cain would have countless potential killers in just a few years.
Every killer in history is a blood relative of mine - and yours, cuz.

Absolute fantasy and imagination, without a shred of Biblical support.

Ignatius a.d. 30–107
Since, also, there is but one unbegotten Being, God, even (that is) the Father; and one only-begotten Son, God, the Word and man; and one Comforter, the Spirit of truth; and also one preaching, and one faith, and one baptism;The Epistle of Ignatius to the Philadelphians Chapter IV
But the Holy Spirit does not speak His own things, but those of Christ, and that not from himself, but from the Lord; even (that is) as the Lord also announced to us the things that He received from the Father. For, says He, “the word which ye hear is not Mine, but the Father’s, who sent Me.” And says He of the Holy Spirit, “He shall not speak of Himself, but whatsoever things He shall hear from Me.” And He says of Himself to the Father, “I have,” says He, “glorified Thee upon the earth; I have finished the work which, Thou gavest Me; I have manifested Thy name to men.” And of the Holy Ghost, “He shall glorify Me, for He receives of Mine.”The Epistle of Ignatius to the Ephesians Chapter IX
For if there is one God of the universe, the Father of Christ, “of whom are all things;” and one Lord Jesus Christ, our [Lord], “by whom are all things;” and also one Holy Spirit, who wrought in Moses, and in the prophets and apostles; The Epistle of Ignatius to the Philippians Chapter I

Adam and Eve were the first man and woman created, but nowhere in the Bible does it say that they were the only ones created.

Actually,
The Bible is not exactly exhaustive in explaining everything that happened during the years before Cain killed Able or the immediate following years. It just hits the highlights.

Humans reproduce exponentially.... meaning once puberty has finished and people reach their majority they can reproduce. (12-16 year olds) Also people (by scriptural accounts) didn't die off so quickly at 60 or 80.
And the society was really wanting the "Seed of the Woman" who was going to grant them access back into the Garden in Eden. So people were definitely looking to make a LOT of Kids. And 16 year old kids were usually having their second child by that point. 30 year old grandparents would be the norm.

So by the time that Cain grabbed a wife she was one of somewhere between 20-30,000 people running about Minimum.

And Adam called his wife's name Eve; because she was the mother of all living. Gen 3:20 (KJV)

Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned: Romans 5:12 (KJV)

And hath made of one blood all nations of men for to dwell on all the face of the earth ... Acts 17:26 (KJV)

ABSOLUTELY Correct all except for the name "Eve". "Eve is the Latin word for mother of all living.
In Hebrew it was "Hawwa".

I double dog dare you to find me the Bible verse where it says God didn’t create 3 headed people!

The scriptures were written for the truths and morals we need to learn. It's not an exhaustive lesson on "How to Build a Universe in six easy steps"
Or "How I populated the Earth"

It's written especially to an ancient people using an archaic completely metaphoric language that had very little in common with the Westernized Society of today. (Except for sin and God....they seem to be constants)

Wherever scripture tells us somebody took a wife, the only thing specific it tells us that he took a woman to become one with, and it's only speculation determining their previous relationship.

Correct....
But the key word here is "took" as almost in a misogynistic manner. It's not very often scriptures mention a Patriarch loving his wife or "joining with a woman in marriage". Maybe as one of his wives was loved and the others just put up with. Job was left with the one wife who thought his breath always smelled bad.

But I tend to think that because of the actions in the Garden where Eve was the first to eat, women became one half step above property. Not really viewed as an equal partner in life. Which is why the word "took" is used....because in a lot of ways her thoughts and attitudes didn't matter concerning who she married.

Great observation. And it brought to my mind, "from dust you were taken, and to dust you shall return." It seems to me there is a residual resentment that she wasn't stronger than he in resisting the temptation to take of the fruit of the totkogae, and that is the only reciprocating sentiment that persists even now, in the general population of course.

How could you possibly know that? Cain and Abel were the first two children born. What makes you think that Cain didn't kill Abel until hundreds of years had passed? How do you know that he didn't kill him before Adam and Eve had ANY other children?

No.

We are created in Gods Image from birth. God is a Triune God, and man is a triune being. Body, soul, spirit.

Do not know what you are trying to say by this:
When you are born again because you receive the Spirit of the Father and Son

God is a Triune God. God the Father, God the Son and God the Holy Spirit
