Does Matthew 24:31 Suggest There Might Be Extra-Terrestrials?

"And He (Jesus) will send His angels with a great sound of a trumpet, and they will gather together His elect from the four winds, from one end of heaven to the other." Matthew 24:31

From "one end of heaven to the other." A curious phrase. In the context of the discourse, was Jesus referring to the 'first" heaven, where the birds fly and we get the air we breathe? Or the "second" heaven, where exists the sun, moon and stars? Or the third" heaven, where God Himself and the angelic host abide? 

In summary judgement I would have to say no; based on the first portion of the same sentence that declares He will send His angels to gather together His elect. By definition only the sons of Adam are eligible to receive redemption that God has provided in the atoning blood of Christ. Meaning that it can only be the redeemed of Christ who are called "His elect".

In the Book of Ruth, we see an excellent example of the principle of the "Kinsman Redeemer", one of the laws codified through Moses at Mt. Sainai. In short, only a blood relative can purchase a debt, or "redeem" a man or woman from a dibilitatingly heavy debt, or slavery, etc..(Leviticus 25:13--25).

  God therefore, using this as a type or "shadow" of things to come, is demonstrating it is only Himself in the person of Yeshua Ha'Meschiak, Jesus Christ, a Son of Man; flesh and blood kin to all of humanity, Who could be counted worthy to redeem fallen man from the due penalty of sin. 

But what would necessitate the angels going from "one end of heaven to the other"? Will ther be Christian astronauts in orbit on the space station? Or did God create an Adam on planets other than earth who also needed redeeming?
