No, we can't speculate, especially on animals resurrected, for there is no support for this in inspiration.

R: Ellen White says God planned to repopulate heaven with human beings.

R: Whether Thomas accepts this or not, the fact is that God is a God of order and He Himself chose the planet man would inhabit. The size of this planet indicates that God designed a given number of human beings to exist in His universe. The same is true for other beings in their respective planets.

R: Well, God Himself will inhabit here in this planet with His redeemed creatures. This is His promise to us. Would you like to live in another planet?

Where do the animals on the New Earth come from if God does not resurrect them? Does He create them? If so, please provide a quote that says so. Rom 8: 19-23 implies animals will be resurrected.

2937. Ktísis; a founding, that is, of a city, colonization of a habitable place. Creation in a pass. sense, what is created, the sum total of what is created (Mark 10:6; 13:19; 1 Pet. 2:13). Denotes particularly the individual creature or what is created (Rom. 1:25; 9:39; Col. 1:15; Heb. 4:13).

GC, I can post links to several scholarly cites that say animals will be resurrected. But this is getting off topic.

The great military commander conquers nations, and shakes the armies of half the world; but he dies of disappointment, and in exile. The philosopher who ranges through the universe, everywhere tracing the manifestations of God's power, and delighting in their harmony, often fails to behold in these marvelous wonders the hand that formed them all. “Man that is in honor, and understandeth not, is like the beasts that perish.” [Psalm 49:20.] No hope of glorious immortality lights up the future of the enemies of God. But those heroes of faith have the promise of an inheritance of greater value than any earthly riches,— an inheritance that will satisfy the longings of the soul. They may be unknown and unacknowledged by the world, but they are enrolled as citizens in the record books of heaven. An exalted greatness, an enduring, eternal weight of glory, will be the final reward of those whom God has made heirs of all things. {GW92 26.2}

This man's aims were no higher than those of the beasts that perish. He lived as if there were no God, no heaven, no future life; as if everything he possessed were his own, and he owed nothing to God or man. The psalmist described this rich man when he wrote, "The fool hath said in his heart, There is no God." Psalm 14:1. {COL 257.1}

In too many households, prayer is neglected. Parents feel they have no time for morning and evening worship. They cannot spare a few moments in which to give thanks to God for his abundant mercies,--for the blessed sunshine and the showers of rain, which cause vegetation to flourish, and for the guardianship of holy angels. They have no time to offer prayer for divine help and guidance, and for the abiding presence of Jesus in the household. They go forth to labor as the ox or the horse goes, without one thought of God or heaven. They have souls so precious that rather than permit them to be hopelessly lost, the Son of God gave his life to ransom them; but they have little more appreciation of his great goodness than have the beasts that perish. {CE 221.1}

It is our wisdom to fear God and to love him with all the heart. He is to be first and last and best in everything. We are not to be like the beasts of the field, who eat and drink, with no thought of God, no idea of gratitude to their Creator for his daily benefits. All of us, as beings blessed of God with reasoning powers, with intellect and judgment, should acknowledge our accountability to God. The life he has given us is a sacred responsibility, and no moment of it is to be trifled with; for we shall have to meet it again in the record of the Judgment. In the books of heaven our lives are as accurately traced as in the picture on the plate of the photographer. Not only are we held accountable for what we have done, but for what we have left undone. We are held to account for our undeveloped characters, our unimproved opportunities. {RH, September 22, 1891 par. 1}

With his own life Christ has bought man, and given him a probation in which to work out his own salvation. God asks his children to live a pure, holy life. He has given his Son that we may reach this standard. He has made every provision necessary to enable man to live, not for animal satisfaction, like the beasts that perish, but for God and heaven. God is not satisfied when human beings live merely a selfish life. Christ died that the moral image of God might be restored in humanity, that men and women might be partakers of the divine nature, having escaped the corruption that is in the world through lust. We are to use no power of our being for selfish gratification; for all our powers belong to him, and are to be used to his glory. He who does nothing to glorify God might better never have been born. Those who live merely an animal life are by precept and example teaching others to leave eternity out of their reckoning. {RH, November 6, 1900 par. 8}

Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water. (1 Peter 3:20)

Bear in mind that your children belong to God, and are to become His sons and daughters. He designs that the families on earth shall be samples of the family in heaven. {AUCR, September 6, 1909 par. 6}

GC: Yes, and I'm sure both of us could post links to scholars claiming there will be marriage in heaven.
