Dear SeekerOfTruth68,
You've got the wrong guy. I don't believe in evolution. I believe in Creationism by God. From grass to trees, to creeping things, to birds, to reptiles to seals, to animals to men, to servants of God in heaven, a very long time, perhaps thousands of years, not millions. But the chain reaction keeps on taking place as we speak, new creatures are starting as grass and moving into bushes, then trees, etc. Listen, I don't believe in evolution, but I do believe that as time passes, you get an upgrade on which earthly/heavenly body God will give you. But it is His Soul discretion, not something by chance from evolution. God is in complete control of it and oversees it. I would guess 12,000 years from grass to heaven. The last life form of course, is servant of God, which is just like being an angel. I think you would be very interested in going to my newest thread (just came out today) called God Creates Good and Evil. You might be amazed. Also, you should definitely give up on Hinduism and serve God as a Christian. You MUST do it. Jesus says, "No man comes to the Father, but by Me." So you will want to believe in Jesus as the Son of God and the Messiah. I know it's a lot to lay on you, but you asked. You need an overhaul.
Any time you want to ask me a question, you can ask it on a post or a PM, depending how personal it is. Hinduism will get you nowhere in life and that's what you'll have to learn in your next life as a person on earth, not a lesser life form. You don't go backwards. And it's okay to eat cattle. Why starve. The cattle does not have your relatives spirit in it so eat and be merry. Hope I've been able to help you.
God Bless You Tons,
MichaelC
