No flame suit required.
A reading of the Bible leads to that conclusion. Although it does not directly say so, the clear inference is that there is only life on Earth - and Man alone was made in the image of God. We now have a very damaged image - since our first parent's disobedience brought sin into the world - but when Christ comes back again, the heavens and earth will be consumed with fire and God will remake the Earth wherein will dwell Righteousness.
2 Peter 3
9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
By the way, Ward and Brownlee are atheists, and came to the same conclusion as Christian astrophysicist Guillermo Gonzales: There aren't any other Earths in this galaxy, and maybe not in the universe at large, but we will never know anything about the latter.
