I'm not really big on this stuff but it it does interest me and I saw something and went crazy with it. Lol.

My math on why "aliens" almost have to exist, or at least some other lifeform.........WE CANT BE ALONE. Thats Crazier than Not being alone........

13.7 Billion yrs Old (supposidly)=Birth of Universe

3.9 Billion years ago=earliest life on Earth

9.8 Billion years between "creation" of universe to first life on earth

9.2 Billion years between "creation" of universe to Homo sapiens

600 million years between 1st life form and 1st "human"


Going by the 600 Mil years, and 9.8 Bil (from creation of universe to first life on earth); Life could've started16 times somewhere (in what seems to be an INFINITE universe) before life on earth ever occurred. Makes you think ........


my math could be a bit sketchy. i have alot more numbers i used but didnt show all/everything. Idk, its crazy. what you guys think? got a formula? opinion? belief? etc...?

Does this prove that there was a global flood and is it also likely that the earth is closer to 6,000 years old instead of the 6 billion year old earth that science has to use in order to give ample time for evolution to take place?

OK so here are the questions, there's 9 of them....... thank you sooooo much for your help....
1. 25= -15 + 8x
2. y / (-6) =2 (the symbol / is divide)
3. -7b = -84
4. a - (-163) = -292
5. (x-8)(2x + 4)=
6. 8 = -32b
7. (6x + 1)(3x + 2)=
8.(5b + 4)(b-8)=
9 (y to the 2nd power -2y + 2)( y + 1 )=

Then I have 2 extra credit questions
Factor: 4x to the 2nd power -13x+3
Solve: 2(x -15) = 60 - X
